Ano a me ka decimals a me nā ana me ia

Mua i loko o ke kula haʻahaʻa, eʻalo nā haumāna me ka hapa. A laila, eʻikeʻia i loko o kēlā me kēia theme like. Poina i ka hana me kēia nui mea hiki ole. No ia mea, ia mea e pono ke ike i ka 'ike e pili ana i ka pono a me ka kekimala hapa. Këia mau manaÿo e noʻonoʻo, i ka papa kuhikuhiE mea - i maopopo nā mea a pau ma ka mea.

No ke aha la hapa iki?

Ke ao nei a puni mākou he o okoa mea. No laila, i loko o ka huliāmahi koi 'ia. Akā, maʻamau o ke ola ka mau pushes e hana me ka māhele o ka mea a me na mea kanaka.

No ka laʻana, kokoleka ua haku o mau cloves. ke kulana kahi i ua hanaʻia heʻumikumamālua rectangles nā kile noonoo. Inā ka mea, ua maheleia i elua, e loaa 6 apana. Ua ua pono māheleʻia, a ekolu. Akā, i ka elima eʻaʻole e hiki iā ia ma ka helu o nā slices o ke kokoleka.

Ma ke ala, i kēia mau Hoʻohana - ua pana aku la ia. A no hoi ia i ko lakou mahele, oia ke ala i oi luna 'helu.

He aha mea he "palapala"?

Keia helu ua haku o na wahi o ka pa alima. Externally, eia kahi mea akaka, e like me ka huina elua hookaawale ia e ka hou a papamoe. Kēia hiʻona ua kapaia fractional. Helu i kākau 'ia ma luna (hema), ua kapaia ka numerator. He aha kū ma ka lalo (pono), ka mea, o ka denominator.

I mea, o ka hapa iki laina mea he hoailona o ka mahele. I ua, ka numerator hiki ke kapa o ka mahele, me ka denominator - mahele waiwai.

He aha mau hapa?

Ma makemakika, ka mea, i elua wale ano: ano a me ka decimals. Me nā haumāna muaʻoe i loko o ke kula haʻahaʻa papa, e hea ana ia ia i ka "ua pana mai." Lua aʻo i loko o 5th papa. A i ka wa a mau inoa hou.

Common hapa - ka poe a pau i kākau i like ka huina elua hookaawale ia e ka ulupaia. No ka laʻana, 4/7. Kekimala - i ka helu ma i ka fractional hapa o ka positional mooolelo, a ua kaawale ia mai ka mea a pau me ka comma. No ka laʻana, 4.7. Nā haumāna i pono e maopopo pono i ka mau examples - ia mea he helu loa okoa.

Kela poe noonoo ole hapa iki hiki ke palapala me ka kekimala. Kēia olelo He kokoke mau oiaio i ka nana e hoole. Aia nā lula e ae mai, e kākau, he pono ole mahele kekimala mahele.

He aha subspecies i kēia mauʻano o ka hapa iki?

Maikaʻi e hoʻomaka ma kekahi mea, e like me ka mea, i ka nānā aku. Ka mea mua, e hele maʻamau hapa. Iwaena o lakou, he 5 subspecies.

1. Pololei. Kona numerator Ua mau emi ma mua o ka denominator.

2. Hewa. Ua numerator, ua oi aku ma mua o paha e like me ka denominator.

3. Contractility / irreducible. Ua hiki e nā pololei a me ka pololei ole. He aha ka oi nui, ina o ka numerator i ka denominator, he pono ole aʻe. Inā loaʻa nō, a laila, e hilinai puunaue i na aoao a elua o ka mahele, i mea, e ho'ēmi i ia.

4. I hui pūʻia. I kona kohu pono pololei (hewa) fractional hapa wahi i ka helu. A ia mea mau ma ka hema.

5. Ke keʻena. Ua Ua hanaʻia o nā hookaawale hapa ma luna o kekahi i kekahi. Oia hoi, ka mea, ua pono ekolu slashes.

Mākou decimals mea wale mau subspecies:

• hope, a laila kekahi ma i ka fractional hapa ua kau palena ia ana (mai ka hope);

• mana loa - helu i kekimala wahi 'aʻole e hoʻopau (' oe ke kākau endlessly).

Pehea e hoohuli i ka kekimala i kaʻena?

Inā ia mea he finite helu, laila, e hoʻohana i ka 'ē aʻe ma muli o ka rula - lohe au, no laila au e palapala aku nei. Ia mea, e pono e heluhelu a kākau mea pono, akā, me ka kekimala wahi, a me ka hou.

E like me ua paipaiʻia i ka denominator, ua pono no ia ia mea mau i kekahi a me kekahi 'Aʻohe. Ka hope pono e kākau i na huahelu ma ka fractional hapa o ka helu nui no.

Pehea e hoohuli decimals i loko o na mahele ina ka helu 'ana ua nalowale, he meaʻole? No ka laʻana, 0,9 paha 0,05. Hope ana keia rula, e huli mai ia oe pono e kākau 'Aʻohe wahi. Akā, ka mea, ua i hoakaka. Ua koe e e kākau wale fractional wahi. Ka mua helu o ka denominator mea like i 10, i ka lua o ka - 100. O ka mea, i kēia mau examples e i ka helu o ka pane: 9/10, 5/100. I ka la mahope huli mai e e hoemi ma ka 5. Nolaila, o ka hopena no ka mea, e e palapala 1/20.

Nā mai kekimala e e maʻamau, ina ka helu hapa mea okoa mai ka 'Aʻohe? No ka laʻana, 5,23 a 13,00108. Ma nā ano he kumu hoʻohālike, ka helu wahi ua heluhelu a me kona waiwai a pau i kākau. Ma ka hihia mua - 5, i loko o ka lua - 13. A laila, e pono e neʻe ana i ka fractional hapa. Ka mea ku paa e hoʻomaka i ka ia hana. Ka helu mua 'ōili mai 23/100, ka lua - 108/100000. pono e hoemi hou i ka lua o ka waiwai. Ma muli o ka holo o kaua i ka poʻe'ē he hapa 5 a me 23/100 13 27/25000.

Pehea e unuhi i ka mana loa kekimala i like?

Inā ka mea, mea ole-papa'āweʻaweʻa kemika,ʻaʻole ia e e hiki, e lawe mai ia i ka hana. Keia mea i aie i ka mea i kēlā kekimala hapa ua mau unuhi a me ka hopena ole papa'āweʻaweʻa kemika.

Ka mea wale nō mea i ua 'ae' ana i hana ai me ka pana - mea e hoopoepoe ia. Akā, laila, i ka kekimala e e kaha like kokekau i mea ole. Ua ua hiki ke hoohuliia mai i loko o maʻamau mahele. Akā, ka mea nana e hoole kaʻina: hoolilo i ka kekimala - aole loa e haawi mai i ka loiloi mua waiwai. I ua, ole-papa'āweʻaweʻa kemika mana loa hapa iki i loko o na mea i unuhi. He pono ke hoomanao.

Pehea e kākau i kekahi mana loa papa'āweʻaweʻa kemika hapa iki i loko o ka palapala o ka maʻamau?

Ma kēia mau huahelu ma hope o ka kekimala wahi mau hōʻike hoʻokahi a oi huahelu e haʻi hou aku. Ka mea, i kapaʻia ka wā. No ka laʻana, 0.3 (3). Here, ka "3" i loko o ka manawa. Ka mea, e pili ana i ka papa o ka naauao, no ka mea, ka mea hiki ke hoohuliia mai i loko o maʻamau hapa.

Ka poe i hui me ka papa'āweʻaweʻa kemika mahele, ka mea, ua ike i ka mea hiki e hala ole a hui. Ma ka hihia mua, i ka wā i hoʻomaka pono o ka kekimala wahi. Ma ka lua o ka - ka fractional hapa hoʻomaka me kekahi nui, a laila, haʻi hou huli no.

A rula e pono e kākau i loko o ka palapala o ka hoʻomaopopo like hapa mana loa kekimala, e e okoa no na ano mau o nā huahelu. Upena papa'āweʻaweʻa kemika hapa puhi wale maʻamau. E like me ka mea hope, e pono e hoohuli ia lakou: i ka numerator o ke kuni i ka manawa, a me ka denominator o ka helu 9, a ua hai hou i na manawa he nui e like me ka huina loaʻa manawa.

No ka laʻana, 0 (5). Ka a pau hapa helu mai malaila, no laila au Pono e hoʻomaka i ka fractional. Ke numerator o ka moolelo 5 me ka denominator i loko o ka 9. ia mea, i ka pane o ka mahele 5/9.

I ka rula e pili ana pehea e kākau i kekahi maʻamau papa'āweʻaweʻa kemika kekimala hapa, e hui pu.

• Helu o fractional huahelu a hiki i ka wā. Ka mea, e hōʻike i ka helu ana o 'Aʻohe hualoaʻa ma ka denominator.

• E nana i ka lōʻihi o ka wā. 9 E i nui ka denominator.

• Record denominator: ka mua eiwa, laila 'Aʻohe hualoaʻa.

• E hoʻoholo i ka numerator, ia mea pono e hoʻopaʻa i ka likeʻole ma waena o nā helu elua. Emi i nā huahelu ma hope o ka kekimala wahi, pu me ka wā. Deductible - ia mea ole au.

No ka laʻana, 0,5 (8) - kākau i ka papa'āweʻaweʻa kemika kekimala hapa iki i loko o ka palapala o ka maʻamau. Ke fractional hapa o ka wā ma mua, he mea hoʻokahi huahelu. 'Aʻohe o ia hoʻi, ma laila e e kekahi. Ma ka ia wā, wale kekahi helu - 8. O ka mea eiwa hoʻokahi. Ia mea, i loko o ka denominator, e kākau 90.

E hoʻoholo i ka numerator o ka 58 pono e unuhi i 5 huli 53. ka pane ana i ka hana e loaʻa i ka palapala ilalo 53/90.

Pehea e unuhi na hapa i decimals?

Ke easiest koho o ka helu, ma a ka denominator o ka helu o ke 10, 100, a no laila, ma luna o. A laila, i ka denominator ua wale i kāpaeʻia, akā, ma waena o ka a pau, a me ka fractional māhele o ka comma.

Aia mau wahi, i hiki i kahi o ka denominator ua hoʻololi 'ia 10, 100, a no laila, ma luna o. D. Eia kekahi laʻana, na helu 5, 20, 25. Ua lawa ka hoonuiia ka 2, 5 a me ka 4, kekahi me kekahi. Just hoʻomāhuahua ka mea nui,ʻaʻole wale nō denominator, akā, i ka numerator ma ka hookahi helu.

No ka mea, a pau nā hihia o ka pono keia mau mea ano rula: puunaue i ka numerator ma ka denominator. finite a papa'āweʻaweʻa kemika kekimala hapa: Ma keia hihia,ʻelua wale nō o nā pane e huli.

Hana a me na hapa

Eia hou kekahi a me ka subtraction

Me ia, e hoʻolauna haumāna ma mua o ka mea e ae. A ma mua i loko o hapa iki o ka ia denominator, a laila okoa. hiki ke hoemi ia ia i kekahi kumumanao General lula.

1. E huli i ka mea liʻiliʻi loa e like me ka lau o ka denominators.

2. Record kumu hou aʻe, he pono ole i pau hapa.

3. E hoonui i na numerators a me denominators o kekahi o kēia mau kumumea.

4. E pelu (unuhi) ka numerator a me ka denominator o ka huina i koe ua hoʻololiʻia.

5. Inā mea emi mai o ka hoemi deductible ka numerator, laila, e pono e loaʻa mai ma mua mākou i kekahi poʻe'ē he helu ai he kupono hapa.

6. Ma ka hihia mua, i ka pau ana o ka pono, e lawe i kekahi. E hoʻohui i ka numerator denominator. A laila, hana subtraction.

7. Ma ka lua o - ia mea e pono e pili i ka rula o ka subtraction o ka liʻiliʻi loa o ka nui. I ua unuhi ia mai ka Module, e unuhi i ka modulus emi iho, a ma muli o, kau i ka hoailona "-".

8. A kokoke nana aku i ka hopena o ka hou (subtraction). Inā e loaʻa ka hewa pana, a laila, ua koho i ka helu 'ana. I mea e puunaue i ka numerator ma ka denominator.

Multiplication a me ka mahele

No ka hapa iki o kā lākou hana, aole ia e pono i alakai i ka pau denominator. Kēia simplifies ka hoʻokō 'ana o ka hana. Akā, ka mea nō hilinai e hahai i ka rula.

1. At multiplication o ka hapa iki mea pono e noonoo i ka helu o ka numerator a me ka denominator. Inā kekahi ka numerator a me ka denominator i ka hoʻomaopopo like ololi, ka mea hiki keʻokiʻia.

2. E hoonui i ka numerators.

3. E hoonui i ka denominators.

4. Inā huli cancellative hapa iki, ka mea, ua hilahila no Nohie hou.

5. I ka wa e puunaue oe, e pono e puku i mua o ka mahele ma ke multiplication, i ka mahele (lua o ka pana) - pana i ke kua (kuapo i ka numerator a me ka denominator).

6. A laila, ke hoomau aku nei me ka multiplication (mai ka anu u 1).

7. I hana kahi eʻalo mai (māhele) pono e ka helu helu, i ka hope o ka nui palapala like kūpono hapa. Ia mea, a me ka denominator 1. A laila, ke hoomau aku e like me ka ho'ākāka 'ia ma luna.

Hana me ka decimals

Eia hou kekahi a me ka subtraction

O ka holo ana, e hiki mau hoohuli i ka kekimala i kaʻena hapa. A ua hana i ka mea i ho'ākāka 'ia, ua kumumanao. Akā, i kekahi manawa ia mea oi kupono e hana me keia hoololi. A laila, na rula o ka hou a me ka subtraction i kēia nui like.

1. E equalize i ka helu o ka huahelu ma ka fractional hapa o ka helu,ʻo ia hoʻi, ma hope o ka kekimala wahi. E hāʻawi ka mea nele i ka helu o nā 'Aʻohe hualoaʻa.

2. Record hapa iki no laila, i kekahi comma ua he comma.

3. E pelu (unuhi) e like me ka helu maoli.

4. E lawe aku i ka comma.

Multiplication a me ka mahele

He mea nui i ka mea, aohe pono i ka Ahaolelo 'Aʻohe hualoaʻa. Mahele manao e waiho i loko o ke ano i loko i ka mea i hāʻawiʻia i loko o ka hana. A laila, e hele aku e like me ke kuka.

1. No ka hoonui hapa, e kakau kekahi ma lalo o ka 'ē aʻe, ka uku, aole he manao i na commas.

2. Hoonui like maoli helu.

3. E kau i ka comma i loko o ka pane ana mai ke kihi akau o ka pane like na huahelu i ka mea e noho ma ka hapa iki o nā kumumea.

4. E puunaue, oe e hoohuli mua o ka mahele: e ia he kūlohelohe helu. E. oia hoi, hoonui ia ma 10, 100, a no laila, ma luna o., Ke kaumaha ma muli o ka helu ana o huahelu ma ka fractional hapa o ka mahele waiwai.

5. ʻO ia ka helu hoonuiia e ka mahele.

6. E ho oka awale i ka kekimala ma ka helu maoli.

7. E kau i ka comma i loko o ka pane i ka manawa o ka hopena o ka mahele a pau.

He aha ina ma ka mea hookahi kumu hoʻohālike, loaʻa nō nāʻano o nā mahele?

Ae makemakika pinepine nui i loko o ka mea e pono ai e hana hana ma ka maʻamau a me decimals. Ma kēia mau hana, ma laila nō nā pāʻoihana. He mea pono e objectively ke kaupaona i ka helu, a koho i ka maikaʻi loa.

Ka mea mua i hele ai: ke manao wale maʻamau kekimala

He pono ina ma mahele a hoolilo o ka hope loa hapa iki i loaa. Inā ma ka liʻiliʻi loa hoʻokahi helu haawi papa'āweʻaweʻa kemika hapa, keia iaoia ua hoʻohana 'ia kēia. Nolaila, a hiki ina oe e e makemake, e hana me na mahele, ka mea i pono, e noonoo ia.

Ka lua o kaʻaoʻao: e kākau decimals maʻamau

Kēia papa hana i kūpono, inā ma ka hapa hope o ka comma i 1-2 huahelu. Inā he mea nui, e hiki i ka nui loa nui na mahele a me nā kekimala 'ikamu ae, e helu i ka hana wikiwiki a me ka maʻalahi. No ka mea, he mau pono e hoohaahaa Loiloi i ka hana a koho i ka easiest ano o ka pilikia.
