Algorithm mahele helu i loko o ke kia ao

Hoike mua papa o ka hana no maoli helu divisible ma ka huahelu hoʻokahi-helu. Ka mea, e ia i ke kumu no ka mahele nunui-kuaiia paha decimals. Wale laila, manao iho e e loli liʻiliʻi, akā, oi ma ia hope:

• Mamua o ka hana lōʻihi mahele, e pono e pohihihi mai kahi o ka mahele a me ka mahele.
• Record mahele. Pono - mahele waiwai.
• E kaha i ka hema a me lalo a puni ka hope kihi.
• Ho oholo i ka hapa mahele, i mea no ka helu ana, e e ka palena haʻahaʻa no ka mahele. IeAUPIIe, IAa IO ka mea, he o he hookahi huahelu, he i kā mākou o elua.
• Koho i ka helu a e ia i ka mua palapala pane. Ka mea, e ia ia i ka helu o ka manawa o ka mahele waiwai ua waiho i loko o ka mahele.
• E palapala i ka hopena o ka hoonui i kēia helu ma ka mahele.
• Kākau ia ma lalo o ka hapa mahele. Hana subtraction.
• E lawe aku i ke koena ma hope o ka huahelu mua o ka hapa i ua ua maheleia.
• Hou, koho i ka helu no ka pane.
• E hana hou i multiplication a me ka subtraction. Inā i ke koena o 'Aʻohe, ka numerator mea ma luna, i ka hāpana ua i. I ole ia, oe a me ke kapuai hookahi: lawe huahelu, e koho i ka helu, hoonui, unuhi.

Pehea e hoʻoponopono i lōʻihi, mahele, ina o ka mahele waiwai i oi aku mamua o hoʻokahi huahelu?

algorithm iho o ka ia e like me ia i ho'ākāka 'ia ma luna. Like mea ka helu o nā huahelu i loko o ka hapa mahele. Ka mea, i kēia manawa ma ka liʻiliʻi loa la oia e mau, akā, ina e emi mai ma mua o ka mahele iho la lakou, i ka hana nui a me ka mea mua ekolu huahelu.

Aia He hoʻokahi hou mea i loko o kēia mahele. Ka nui, e hoike ana i ke dala, a wāwahi ia i ke Kii kekahi manawa puunaueia e kekahi mahele. Alaila, manao iho la e kaila kekahi helu ma ka mea. Akā, i kēia pane mea pono e hoopakele Aʻohe. Inā ka mahele ua lawe mai huahelu-ekolu helu i loko o ka kolamu, oe e pono e lawe hou aku ma mua o nā huahelu. A laila, hoʻolauna i ka rula: 'Aʻohe hualoaʻa ma ka pane pono e kekahi emi mai ma mua o ka helu ana o huahelu o ka wāwahi.

E hoomanao i keia mahele hiki ia i kumu hoolike - 12082: 863.

• Kāpili divisible helu o 1208. It ia i ka helu 863 ua kau wale kekahi manawa. No laila, ma ka pane nui lako 1, a me ka mooolelo 863 i ka 1208.
• Ma hope unuhi i ka loaa koena 345.
• I ka mea nana e lawe aku i ka huahelu 2.
• Mawaena o ka 3452 quadruple kupono 863.
• Lau e e kākau hoʻi. ¶ A, i ka wa a hoonuiia e 4 ua loaa like keia helu.
• Ke koena ma hope o ka subtraction mea Aʻohe. Ia mea, no ka papa ana.

I ka pane e ia i ka helu i loko o Laʻana 14.

He aha ina ka mahele welau ma Aʻohe?

A i 'ole kekahi mau' Aʻohe hualoaʻa? Ma keia hihia, he 'Aʻohe koena ua loaa, a ma ka mahele nō' Aʻohe hualoaʻa. Hana ole o ka manao, a pau ka hiki'ē ma mua o ka mea paha e huhūʻoukou. Aloha wahi e pane i nā 'Aʻohe hualoaʻa i i ole kaawale.

No ka laʻana, ka mea, ua pono e puunaue i ka 400 divisible ma 5. kāpili 40. Ua fits 8 manawa elima. No laila, ma muli o ka mooolelo nui 8. ke koena koe I unuhi. Ia mea, o ka mahele ua ana, akā, i loko o ka mahele, he 'Aʻohe. Ka mea, e loaa ia ia e wahi ana i ka mai. Penei, ma ka mahele ana i 400 ma ka 5 me 80 'ana e haʻalele.

He aha ina e pono ai e puunaue i ka kekimala?

Hou, keia helu mea like me ke kino, ina i ka comma hookaawale ana i ka helu 'ana, mai ka fractional. Ua paipai i ka mahele ana o decimals i loko o ke kia ao i like me ia i ho'ākāka 'ia ma luna.

Ke wale koena unuhi o ka'ikamu me ka comma. Kona manao, e kau hoʻi i koke wāwahi i ka huahelu mua o ka fractional hapa. Ma kekahi aoao, ka mea hiki ke olelo aku ia ma luna o ka papa o ka mea a pau hapa - ka comma a me ka hoʻomau 'ana i ka hoʻoponopono' hou.

Ma ka hoʻoponopono o examples o lōʻihi māhele me decimals pono e hoʻomanaʻo i loko o ka hapa hope o ka kekimala wahi hiki e wahi ai i kekahi helu o nā 'Aʻohe hualoaʻa. I kekahi manawa, he mea pono e dodelit helu a hiki i ka hopena.

Mahele o nā decimals

Ua i mea huikau. Akā wale nō i mua. Ma hope o nā mea a pau, pehea e hana lōʻihi mahele i ka hapa iki o ka helu, ia mea ua maopopo. No laila, ua pono e lawe i kēia hana a hiki i ka ua mau palapala.

E ia maʻalahi. E hoonui i ka mahele elua o ka 10, 100, 1 000 a me 10 000, a paha he miliona, ina koi 'ia ma ka hana. Modifier manao e koho ma ka muli o ka nui o na 'Aʻohe hualoaʻa waiho i loko o ka kekimala hapa o ka mahele waiwai. ʻo ia hoʻi, i ka hopena, e ia i ke kaʻana like 'ana, e i eʻolokaʻa mai i ka helu maoli.

A ka mea, e ia i loko o ka poʻe hewa nui hihia. Aia hoʻi, ka mea i hiki i ka mahele o keia hana, e ia ka helu. A laila, e e hoemiia ka hana o ka pāʻoihana a hiki i ka mahele loa o ka mahele ana i ka simplest Lolina: ana me maoli helu.

Me lakou i mea hoike, puunaue ka 3.2, 28,4:

• Mua, ka mea, pono e hoonui i ka 10, e like me ia ma ka lua o ka helu ma hope o ka kekimala wahi he mea hoʻokahi wale nō huahelu. Multiplication haawi 284 a me 32.
• Ka mea, Ua manao ia e maheleia. A me nā mea a pau i koke ka helu 32 284.
• na helu mua koho i ka pane mai o 8. Mai hoonui loa ia huli mai 256. ke koena o 28.
• Ka mahele ana i ka mea a pau loa i luna, a ma muli o nui comma.
• 0 lawe aku i ke koena.
• Hou, lawe 8.
• Koena: 24. No kēia kaila kekahi 0.
• Ano, e pono e lawe 7.
• Ka multiplication hopena - 224 koena - 16.
• Haehae ia kekahi 0. E 5 a me ka loaa wale 160 ke kaulike - 0.

Ka mahele pau. Hopena Laʻana 28,4: 3.2 o 8,875.

He aha ina o ka mahele, he 10, 100, 0,1, a 0,01?

Like pono me me ka multiplication, lōʻihi mahele ua i koi 'ia. Aloha hoolilo i ka comma ma ke ala e hiki aku akau no i kekahi helu o nā huahelu. A, e like me keia rula hiki ke wehe pilikia examples me nā integers a me nā kekimala hapa.

No laila, inā e pono e puunaue ka 10, 100 a me 1000, i ka comma ua hoololiia a hiki i ka waiho ma ka helu o nā huahelu, ehia na 'Aʻohe hualoaʻa ma ka denominator. I ka mea, i ka wa a ka helu mea divisible ma ka 100, he comma E e 'oni iki i ka haʻalele e nā huahelu. Inā ka mahele - he helu maoli, ka papahana lawe i ka comma mea waiwai i ka hopena.

Kēia hana i haawi mai i ka ia hopena me ina ka helu i ia e hoonuiia e 0,1, 0,01 a 0,001. Ma kēia mau examples nui, ka comma ua hoololiia a hiki i ka haʻalele ma ka helu o nā huahelu like me ka lōʻihi o ka fractional hapa.

I ka mahele ana ma ka 0.1 (a me ka 'ole. D.), A hoonuiia ka 10 (a me ka' ole. D.) Comma pono neʻe i ka akau ma kekahi huahelu (a elua, ekolu, ke kaumaha ma muli o ka helu o nā 'Aʻohe hualoaʻa a lōʻihi o ka fractional hapa).

Ua mea waiwai 'ana i kumumanaʻo i ole e lawa i ka helu o ka huahelu ma ka maheleʻikepili i. A laila, ma ka hema (i loko o ka a pau loa) a me ka akau (ma hope o ka kekimala wahi) hiki ke wahi i ka mea o kaʻalā iā 'Aʻohe hualoaʻa.

I ka māhele o ka hou decimals

Ma keia hihia,ʻaʻole ia e e hiki ke loaa i ka kiko'ī pane ma lōʻihi mahele. Pehea e hoʻoponopono i ka hana, ina oe halawai kekahi hapa iki me ka manawa? Eia ka mea, ua ea ae ka hana, e neʻe ana i na mahele. A laila lawe aku i ko lakou mau papa, e like me ka rula mua? Anoee.

0 Pono e mahele e laʻa me, (3) 0.6. Ka mua mahele - papa'āweʻaweʻa kemika. Ua ia iho i loko o ka mahele 3/9, a ma hope o ka ho'ēmiʻana haawi 1/3. Ka lua o ka hapa - ka kekimala hope loa. Kona mooolelo o ka maʻamau, a hiki maʻalahi: 6/10, i mea like me 3/5. Rule o ka mahele o ka hapa i hoakaka ia e puku i ka papa ma ka hoonui i ka mahele waiwai - retroactively. I mea ua hoemi he laʻana o ka multiplication i 1/3 i 5/3. Ke pane He 5/9.

Inā i ke kumu hoohalike o keʻano hapa ...

A laila, loaʻa nō kekahi mau pāʻoihana. Mua, e like me ka mahele, e hiki ho'āʻo i ka unuhi i loko o kekimala. A laila māhele i mau decimals e like me ka algorithm ho'ākāka 'ia ma luna.

Ka lua, kēlā finite kekimala hapa iki hiki ke palapalaia e like me ka maʻamau. Wale ka mea, ke i mau pono. Ka hapa nui o kēia mau mahele e nui. A mea cumbersome ka pane. No laila, ka mea mua hoʻokokoke ua noʻonoʻo hou mau pahuhopu.
