Pulogalamu ya peresenti ndiyo njira yoimira kachigawo komwe chiwerengerocho chagawika magawo zana. Mwachitsanzo, kunena kuti chinthu chili ndi mafuta 30%, zikutanthauza kuti ngati titagawa magawo 100, 30 mwa iwo akhoza kukhala mafuta.
Pulogalamu ya % chizindikiro Ndizofanana pamasamu ndi 0.01 zomwe zikutanthauza kuti 1% ndiyofanana ndi 0.01.
A kachigawo ndi ubale pakati pazambiri. Chiwerengerocho chimakulolani kuyerekezera ndalama zosiyanasiyana polemekeza chiwonkhetso.
Kuti tipeze kuchuluka kwa kuchuluka konse (Y) komwe kuchuluka kwa X kumayimira, tiyenera kugawa X ndi Y, kenako ndikuchulukitsa ndi 100.
Mwachitsanzo, ngati chakudya chonse ndi magalamu 40 ndipo chili ndi magalamu 15 a mafuta:
- 15/40 x 100 = 37.5%. Ndiye kuti, chakudyacho chili ndi mafuta a 37.5%.
Kuti mudziwe kuchuluka kwenikweni komwe kumayimira peresenti P ya Y yonse, chulukitsani P ndi Y yonse, kenako mugawane ndi 100. Mwachitsanzo, ngati mukufuna kudziwa kuchuluka kwa 30% ya 120 ndi:
30 x 120/100 = 36. Ndiye kuti, 30% ya 120 ndi 36.
Chiwerengero chambiri chitha kuwonetsa ndalama zochepa kwenikweni. Mwachitsanzo, ngati 90% ya supuni ndi shuga, atha kukhala magalamu 1.8 okha a shuga. Ngakhale 15% ya paketi ya shuga itha kukhala magalamu 150. Chifukwa chake, kuti mudziwe kuchuluka kwake ndikofunikira kudziwa kuti kuchuluka kwake kumayesedwa bwanji.
Itha kukuthandizani: Chizindikiro% ndi chiani ndipo chimawerengedwa bwanji?
