Yechim qadamlari

9 ni \frac{54}{6} kasrga o‘giring.

$$\frac{7}{2}\left(\frac{13}{6}+\frac{54}{6}\right)$$

\frac{13}{6} va \frac{54}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7}{2}\times \frac{13+54}{6}$$

67 olish uchun 13 va 54'ni qo'shing.

$$\frac{7}{2}\times \frac{67}{6}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{2} ni \frac{67}{6} ga ko‘paytiring.

$$\frac{7\times 67}{2\times 6}$$

\frac{7\times 67}{2\times 6} kasridagi ko‘paytirishlarni bajaring.

$$\frac{469}{12}$$

Omil

$$\frac{7 \cdot 67}{2 ^ {2} \cdot 3} = 39\frac{1}{12} = 39,083333333333336$$
