Thaum ib yam twg yog proportional rau lwm yam, nws tsis txhais hais tias qhov tseem ceeb sib npaug, tsuas yog hais tias lawv hloov nrog kev hwm. Qhov tsis tu ncua ntawm proportionality ua tus multiplier.
Puas yog proportional the same as equal?
Raws li adjectives qhov txawv ntawm proportional thiab sib npaug
yog tias proportional yog ntawm ib tug constant ratio (rau) ob qhov loj (tus lej) yog hais tias proportional yog qhov thib ob sib txawv hauv kev sib raug zoo ntawm tus lej rau thawj zaug thaum sib npaug yog (label) tib yam hauv txhua qhov kev hwm.
Puas kev sib raug zoo yuav tsum sib npaug?
kev sib raug zoo yog kev sib raug zoo ntawm ob qhov sib txawv uas lawv qhov sib npaug.
Yuav ua li cas sib npaug?
Yog qhov piv (yx) ntawm ob qhov sib txawv (x thiab y) yog sib npaug rau qhov tsis tu ncua ( k=yx), ces qhov sib txawv ntawm tus lej ntawm qhov piv (y) tuaj yeem yog cov khoom ntawm lwm qhov sib txawv thiab qhov tsis tu ncua (y=k ⋅ x). Hauv qhov no, y yog hais ncaj qha proportional rau x nrog proportionality tas li k.
Ib qho piv txwv ntawm ncaj qha proportional yog dab tsi?
Thaum ob qhov ntau yog ncaj qha proportional nws txhais tau hais tias yog ib qho khoom nce los ntawm ib feem pua, lwm qhov ntau nce los ntawm tib feem pua thiab. Ib qho piv txwv yuav yog li nqi roj nce nqi, khoom noj khoom haus nce nqi.
