Txoj Kev 2 Simplifying tus feem
- Sau tus feem ntawm ib daim ntawv. Muab 14 hla 28 nrog ib kab nyob nruab nrab.
- Sau qhov sib npaug. Muab ib sab faib rau sab xis ntawm txhua tus lej.
- Faib tawm ob tus lej. Faib 14 thiab 28 los ntawm 14.
- Sau cov lus teb raws li a feem .
- Tshawb xyuas koj txoj haujlwm.
Qhov sib thooj, txoj kev tshem tawm yog dab tsi?
Lus Txhais Ntawm Kev rho tawm Kev ua haujlwm ntawm tshem tawm tawm ntau yam tseem ceeb hauv tus lej thiab tus denominator yog hu ua Kev rho tawm.
Tsis tas li ntawd, ua li cas koj rho ib feem? Txoj Kev 2 Simplifying tus feem
- Sau cov feem ntawm ib daim ntawv. Muab 14 hla 28 nrog ib kab nyob nruab nrab.
- Sau qhov sib npaug. Muab ib sab faib rau sab xis ntawm txhua tus lej.
- Faib tawm ob tus lej. Faib 14 thiab 28 los ntawm 14.
- Sau cov lus teb ua ib feem.
- Tshawb xyuas koj txoj haujlwm.
Ib yam li ib tug yuav nug, koj ua li cas yooj yim cov feem?
Yuav ua li cas kom yooj yim ib feem:
- Nrhiav ib qho tseem ceeb ntawm tus lej thiab tus lej.
- Faib ob qho tib si tus lej thiab tus denominator los ntawm commonfactor.
- Rov ua qhov txheej txheem no kom txog thaum tsis muaj cov xwm txheej ntau ntxiv.
- Cov feem yog yooj yim thaum tsis muaj ntau yam muaj nyob.
Yuav ua li cas koj rho ib feem ntawm ib qho kev sib npaug?
Yuav kom daws tau qhov sib npaug uas muaj cov feem:
- Nrhiav qhov qis tshaj plaws ntau yam ntawm cov denominators uas paub tias yog qhov qis tshaj plaws denominator (LCD).
- Tshem tawm cov feem los ntawm kev muab ob sab ntawm qhov sib npaug los ntawm LCD.

Yuav ua li cas koj tig ib feem rau hauv nws daim ntawv yooj yim?
Daim Ntawv Simplest (fractions) Ib feem yog nyob rau hauv daim ntawv yooj yim tshaj plaws thaum sab saum toj thiab hauv qab tsis tuaj yeem ua me me, thaum tseem yog tus lej tag nrho. Txhawm rau kom yooj yim ib feem: faib sab saum toj thiab hauv qab los ntawm tus lej loj tshaj plaws uas yuav faib ob tus lej raws nraim (lawv yuav tsum nyob txhua tus lej)
Yuav ua li cas koj sau ib feem raws li ib tug khoom ntawm ib tug tag nrho cov zauv thiab ib feem feem?
Cov cai los nrhiav cov khoom ntawm ib feem feem thiab tag nrho tus lej Peb xub sau tag nrho cov lej ua ib feem, piv txwv li, sau nws faib los ntawm ib qho; Piv txwv li: 7 yog sau ua 71. Peb mam li muab cov zauv. Peb muab cov denominators. Yog tias yuav tsum tau ua kom yooj yim, nws ua tiav thiab tom qab ntawd peb sau cov feem kawg
Yuav ua li cas rho tawm rho tawm haujlwm?
Rho dependent termination yog ib qho ntawm ob hom kev txiav tawm hauv prokaryotic transcription, lwm qhov yog intrinsic (los yog Rho-independent). Tom qab khi rau cov saw tshiab RNA, ρ qhov tseem ceeb txav mus raws cov molecule hauv 5'-3' kev taw qhia thiab txhawb kev sib cais los ntawm DNA qauv thiab RNA polymerase
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
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
