Cov yam ntxwv sib piv ntawm ob qhov ntau thiab tsawg, qhia ua ib qho ntawm ib qho txawv ntawm qhov tsis sib thooj, hu ua lawv feem. Yog tias ib qho ntawm tus nqi sib piv (lossis lawv cov lej) raug muab sib npaug rau ib puas feem pua, tom qab ntawd qhov sib txawv ntawm cov nuj nqis kuj tseem tuaj yeem ua raws feem pua. Qhov kev sib piv no yuav raug xa mus ua feem pua.
Cov Lus Qhia

Tsim cov teeb meem ua kom raws li cov cav, yog tias koj tsis raug sau daim phiaj xwm rau. Piv txwv li, yog tias muaj cov ntawv xeem (80 cov lus teb raug thiab 20 tsis raug), ces 100 feem pua yuav tsum tau ua tus lej ntawm qhov paub tias muaj nuj nqis (80 + 20 = 100). Raws li qhov no, qhov feem pua ntawm ob qhov tseem ceeb tuaj yeem txiav txim siab li 80% txog 20%. Thiab yog tias, raws li qhov xwm txheej ntawm cov teeb meem, tus naj npawb ntawm cov lus teb kom yog (80) thiab tus naj npawb ntawm cov lus nug (100) tau paub, tom qab ntawd ib qho ntawm cov paub muaj nuj nqis yuav tsum tau ua 100 feem pua, thiab tsis yog lawv cov lej. Muaj kev txiav txim siab tias tus nqi twg yuav tsum raug suav tias yog ib puas feem pua tus qauv, koj tuaj yeem txuas mus rau kev siv xam ntawm qhov tshwm sim.

Pom qhov sib piv ntawm ob qhov tseem ceeb los ntawm kev sib faib ib qho ntawm lwm tus, thiab tom qab muab cov txiaj ntsig los ntawm 100 los qhia qhov feem pua no ua ib feem pua. Yog tias nws tsis tuaj yeem ua cov kev suav zoo hauv koj lub taub hau, tom qab ntawd siv, piv txwv li, lub laij lej nkag mus rau hauv Google search engine. Txhawm rau ua qhov no, mus rau nplooj ntawv ntiag tug ntawm lub vev xaib no thiab ntaus cov ntawv thov tsim nyog. Piv txwv li, yog tias koj xav suav qhov feem pua ntawm cov lus teb yog (37) rau lawv tus lej (52), tom qab ntawd nkag mus "37/52 * 100" thiab koj yuav pom cov lus teb uas yog (71.1538462).

Siv, piv txwv li, ib daim ntawv kho me nyuam phau ntawv sau Microsoft Excel yog tias koj xav ua yam tsis muaj Is Taws Nem. Tom qab tsim tawm nws, sau cov ntaub ntawv xav tau rau kev suav. Piv txwv li, hauv thawj lub xov tooj, sau tus naj npawb ntawm cov lus teb kom yog (37), thiab hauv ob, tus naj npawb tag nrho ntawm cov lus teb (52). Hauv lub xovtooj thib peb, nyem qhov kos npe sib npaug, tom qab ntawd nias thawj lub xovtooj, nias rau sab tom ntej (slash) yuam, nyem rau ntawm tes thib ob, thiab nias Enter. Tus kws sau ntawv yuav suav qhov yooj yim ntawm ob qhov tseem ceeb. Txhawm rau hloov nws mus rau feem pua, muab cov ntawv qaij no ib feem pua. Ua li no, nyem nws txoj thiab xaiv "Hom" kab hauv cov ntawv qhia zaub mov. Hauv kab "Number format", nyem kab "Feem Npaum" thiab hauv "Naj npawb ntawm lej" chaw sau lub chaw lej kaum uas cov txiaj ntsig yuav tsum sib npaug. Tom qab ntawv nyem khawm "OK".
