Fassara zuwa masu jujjuya - "kowace mota ta biyu" na nufin kashi hamsin (50%).
Amsa daidai shine: rabin miliyan na motoci sun girmi shekaru biyar.

Kashi daya cikin dari ma yana nufin dari bisa dari. Daga misali na sama - ɗari (1%) daga miliyan zai zama dubu dari. \( x = \frac{1 000 000}{100} = 100 000 \\ \)

Kashi dari

\( Kashi = Daraja / TotalValue \cdot 100 \\[1ex] \)
Misali: Nawa kaso 5 ne cikin motoci 10
\( Kashi = (5 / 10) \cdot 100 \\ Kashi = 50\% \)

{{ partSecond }} na {{ wholeSecond }} shine {{ percentResult }}%

Darajar darajar

\( Daraja = Kashi \cdot (TotalValue / 100) \\[1ex] \)
Misali: Mota nawa ne 10% na 50
\( Daraja = 10 \cdot (50 / 100) \\ Daraja = 5 \, motoci \)

{{percentFirst}}% na {{wholeFirst}} shine {{ valueResult }}

Jimlar darajar dabara

\( TotalValue = Daraja \cdot (100 / Kashi) \\[1ex] \)
Misali: Menene Vimar Duka idan motoci 5 suka kasance 50%
\( TotalValue = 5 \cdot (100 / 50) \\ TotalValue = 10\; motoci \)
