Yuav kom ua daws proportions nrog cov lej sib xyaw yooj yim dua, yooj yim tig lub sib xyaw rau hauv qhov tsis tsim nyog feem . daws proportions nrog cov lej sib xyaw los ntawm kev siv tus lej sib npaug nrog kev pab los ntawm tus kws qhia lej hauv daim vis dis aus pub dawb no proportions hauv lej.
Xav txog qhov no, koj ua li cas kom yooj yim qhov piv txwv?
Yuav Ua Li Cas Simplify qhov ratio A: B thaum A thiab B yog tag nrho cov lej
- Sau cov xwm txheej ntawm A.
- Sau cov xwm txheej ntawm B.
- Nrhiav qhov zoo tshaj plaws ntawm A thiab B, GCF (A, B)
- Faib A thiab B txhua los ntawm GCF.
- Siv tag nrho cov txiaj ntsig los sau qhov sib piv hauv daim ntawv yooj yim tshaj plaws.
Tsis tas li ntawd, koj ua li cas daws cov feem sib xyaw? Txhawm rau hloov cov feem tsis tsim nyog rau ib feem sib xyaw, ua raws li cov kauj ruam no:
- Faib tus lej los ntawm tus denominator.
- Sau tag nrho cov lus teb.
- Tom qab ntawd sau ib yam dab tsi ntxiv rau saum tus denominator.
Yog li ntawd, tus piv puas tuaj yeem yog tus lej sib xyaw?
A sib xyaw feem muaj tag nrho tus lej ntxiv ib feem. Koj ua tau convert ib sib xyaw feem rau a piv los ntawm kev nthuav qhia cov feem hauv "tsis tsim nyog" daim ntawv. Qhia koj cov lus teb rau hauv piv daim ntawv. Koj ua tau sau cov piv nyob rau hauv ntau yam sib txawv.
Yuav ua li cas hloov cov feem tsis tsim nyog rau cov zauv sib xyaw?
Piv txwv li: Hloov cov feem tsis tsim nyog 402/11 mus rau ib qho sib xyaw
- Faib tus lej los ntawm tus denominator. Faib 402 los ntawm 11, uas sib npaug 36 nrog qhov seem ntawm 6.
- Nrhiav tus lej tag nrho. Tus lej tag nrho yog tus lej ntawm lub sijhawm uas tus lej faib rau hauv tus lej.
- Ua tus seem ntawm tus lej tshiab.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Yuav ua li cas koj daws cov kab zauv sib npaug los ntawm graphical method?
Ib qho kev daws teeb meem tuaj yeem ua tau los ntawm tes (ntawm daim ntawv duab), lossis nrog kev siv lub tshuab xam zauv. Graphing ib qhov system ntawm linear equations yog yooj yim li graphing ob kab ncaj. Thaum cov kab yog graphed, qhov kev daws yuav yog tus (x, y) xaj khub uas ob kab sib tshuam (hla)
Koj yuav daws li cas feem pua ntawm cov proportions?
Hauv kev faib ua feem ntawm cov khoom sib npaug sib npaug: Yog li 3 zaug 100 yog sib npaug rau 4 npaug ntawm PERCENT. Qhov ploj lawm PERCENT sib npaug 100 zaug 3 muab faib los ntawm 4
Yuav ua li cas koj daws cov zauv complex thiab xav txog zauv?
Cov lej nyuaj muaj daim ntawv a + bi a + b i, qhov twg a thiab b yog cov lej tiag tiag thiab kuv yog lub hauv paus square ntawm & rho tawm 1. Txhua tus lej tiag tuaj yeem sau ua tus lej nyuaj los ntawm kev teeb tsa b = 0. Cov lej xav tau muaj daim ntawv bi thiab tseem tuaj yeem sau ua tus lej nyuaj los ntawm kev teeb tsa a = 0
Yuav ua li cas koj ntxiv rho tawm ntau thiab faib cov feem thiab cov zauv sib xyaw?
Cov zauv sib xyaw thiab cov zauv tsis zoo Muab cov zauv los ntawm tag nrho cov lej. Ntxiv cov khoom rau tus lej. Tus lej no yuav yog tus lej tshiab. Tus denominator ntawm qhov tsis tsim nyog feem yog tib yam li tus denominator nyob rau hauv thawj cov zauv sib xyaw
