Ob peb txoj kev los xam qhov feem pua ntawm tus xov tooj (thiab ib tug zoo xws li cov hom hauj lwm)

Muab xam los ntawm cov feem pua ntawm cov xov tooj - ib tug hauv paus tseeb hais tias tag nrho cov coj qhov chaw nyob rau hauv lub tsev kawm ntawv nyob rau hauv lub lej qhia. Tab sis qhov no tsis txhais hais tias tag nrho cov tau sai dlua nws yooj yim. Nyob rau hauv qhov tseeb, lub ntsiab lus yog yooj yim, cov tseem ceeb tshaj plaws - mus paub cov pov thawj txoj kev ntawm xam nyob rau ib feem ntawm tag nrho cov thiab cov kev txaus siab ntawm tag nrho cov.

1% - muaj ib feem puas ntawm tag nrho cov, yog li ntawd paub qhov no tus nqi yuav yooj yim xam tus nqi ib feem. Piv txwv li, 15% ntawm 60 yuav xam raws li nram no: muab 60 rau 100 feem pua. Ces 1% - yog 60/100 - 0.6. 15%, yog li, roos - 0.6 * 15 = 9. Qhov no yog thawj txoj kev los laij cov feem pua ntawm tus xov tooj.

Qhov thib ob txoj kev - mus cuag kev faib ua feem. 15 txog rau lub 100 raws li koom X 60, uas yog 15/100 = x / 60. Daws kev faib ua feem ua los nyob rau hauv ob txoj kev:

1. Hloov mus rau ib qho kev qhia x = 15 * 60/100. Ib zaug ntxiv, nws puv tawm: x = 9.
2. Ua kom lwm tus hloov dua siab tshiab nyob rau hauv cov kauj ruam 2: 100x = 15 * 60, uas yog, nyob rau hauv lub proportions ntawm multiply crosswise. Los ntawm no qhia, peb tau txais hauv qab no: 100X = 900. Yog li ntawd, x = 9.

Yog hais tias koj xav tau kom paub tseeb seb yog dab tsi feem pua ntawm tus xov tooj ntawm lwm cov xov tooj, cov mis no kuj yog heev yooj yim. Noj piv txwv li cov zauv 70 thiab 13. Cia 70 - yog 100%, thiab 13 - x. Ces 13/70 = x / 100. Daws tau qhov kev faib ua feem tej zaum yuav twb paub txoj kev.

Lub 70 * 13 = 100; 70s = 1300; Yog hais tias npawv mus rau lub thib ob decimal qhov chaw, nws hloov tawm hais tias x = 18,57%.

Yog hais tias koj paub ib tug tej yam feem pua ntawm cov xov tooj thiab yuav tau mus nrhiav ib tug xov tooj, thiab qhov teeb meem no yuav daws nkaus.

Piv txwv li, 16% - yog 32. Yuav ua li cas yog lub integer? Dua compose kev faib ua feem: 16% txog 100%, raws li zoo raws li 32 x. 16/100 = 32 / x; 16X = 3200; x = 3200/16 = 200.

Yog hais tias tus mob no yog hais tias qhov teeb meem uas tus xov tooj ntawm ib tug yog ib tug tej yam feem pua ntawm tus xov tooj ntawm B, uas yog tsim nyog los mus laij lub thov lwm yooj yim heev mis. A / B * 100% - qhov no yuav tau cov lus teb. Piv txwv li, koj yuav tau mus nrhiav seb yog dab tsi feem pua ntawm tus xov tooj 87 yog tus naj npawb 329.

Xam cov kev tshwm sim ntawm lub mis, peb tau 87/329 * 100% = 26,44%. Yog hais tias cov mis yog tsis nco qab lawm nyob rau ntawm lub lub sij hawm, los pab rov qab los proportions: 87 yog hais txog mus rau lub 329, raws li cov x hais txog 100%, uas yog 87/329 = x / 100. Converting no faib ua feem, peb tau txais 329h = 87 * 100; 329h = 8700; x = 8700/329 = 26,44%.

Zoo, qhov nyuaj proportions nyob rau hauv yuav luag tag nrho cov yeej ib txwm nyob rau hauv lub pob ntseg, thiab nyob rau hauv kuv lub taub hau: ib-thib tsib - yog 20%, ib feem kaum - 10%, ib nrab thiab ib tug peb lub hlis twg - 50% thiab 25% feem. Rau ib txhia, nws yog ntau yooj yim thiab dlaim phaj xav feem ntau, thiab ib tug neeg yog yooj yim rau koj khiav lag luam feem pua. Qhov loj qhov sib txawv ntawm ib tug thib ob thiab 50% ua tsis tau.

Nrog ib tug xam zauv thiab ua yuav yooj yim, vim hais tias muaj txawm tias ib tug tshwj xeeb khawm uas tso cai rau koj los mus laij lub paj.

Ntawm cov hoob kawm, tag nrho cov ntawm cov kev pab raws qib - phiaj xwb lub hom phiaj. Tab sis los xam qhov feem pua ntawm tus xov tooj yuav tsum tau nyob rau hauv lub neej. Ntawm kev muag khoom rau saib seb ib tug 30% luv nqi mus tsuab ntawm ib tug tshaj plaws, los yog nws yog ib tug me me npaum li cas. Koj yuav nrhiav tau tawm yog dab tsi tus nqi mus txo, raws li zoo raws li recheck sellers - vim hais tias lawv feem ntau yog inattentive buyers thiab taw tes rau tus nqi tag yog heev txaus nyiam cov nuj nqis.

Xam qhov feem pua ntawm tus xov tooj tej zaum yuav tsum tau, thiab lub xam ntawm cov se, ntawm chav kawm, rau cov neeg uas taug qab tej yam. Thiab, ntawm chav kawm, cov kev txaus siab muab xam tas li ntsib LAGLUAM, economists, stockbrokers thiab tshuaj ntsuam. Nyob rau hauv qhov tseeb, txawm tias ib tug niam tsev lossi tau nrog kev txaus siab, tsis muaj txawm pom.

Nyob rau hauv luv luv, lub ntsiab lus yog yooj yim, tab sis yog nws mas nyuaj heev thaum xub thawj siab ib muag. Txawm li cas los, thaum nws los to taub, paub tab txog kev xam ntawm kev txaus siab nyob rau hauv lub xov tooj thiab nyob rau hauv tag nrho cov feem, zoo li noob. Koj tsuas muaj mus sau thiab ib tug me ntsis loaf.
