Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{4} ni \frac{5}{3} ga ko‘paytiring.

$$\frac{7\times 5}{4\times 3}+\frac{9}{8}$$

\frac{7\times 5}{4\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{35}{12}+\frac{9}{8}$$

12 va 8 ning eng kichik umumiy karralisi 24 ga teng. \frac{35}{12} va \frac{9}{8} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{70}{24}+\frac{27}{24}$$

\frac{70}{24} va \frac{27}{24} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{70+27}{24}$$

97 olish uchun 70 va 27'ni qo'shing.

$$\frac{97}{24}$$

Omil

$$\frac{97}{2 ^ {3} \cdot 3} = 4\frac{1}{24} = 4,041666666666667$$
