Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{16} ni \frac{1}{2} ga ko‘paytiring.

$$\frac{5}{8}-\frac{7\times 1}{16\times 2}$$

\frac{7\times 1}{16\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{5}{8}-\frac{7}{32}$$

8 va 32 ning eng kichik umumiy karralisi 32 ga teng. \frac{5}{8} va \frac{7}{32} ni 32 maxraj bilan kasrlarga aylantirib oling.
