Yechim qadamlari

63 hosil qilish uchun 7 va 9 ni ko'paytirish.

$$\frac{63+2}{9}\times \frac{1\times 11+2}{11}$$

65 olish uchun 63 va 2'ni qo'shing.

$$\frac{65}{9}\times \frac{1\times 11+2}{11}$$

11 hosil qilish uchun 1 va 11 ni ko'paytirish.

$$\frac{65}{9}\times \frac{11+2}{11}$$

13 olish uchun 11 va 2'ni qo'shing.

$$\frac{65}{9}\times \frac{13}{11}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{65}{9} ni \frac{13}{11} ga ko‘paytiring.

$$\frac{65\times 13}{9\times 11}$$

\frac{65\times 13}{9\times 11} kasridagi ko‘paytirishlarni bajaring.

$$\frac{845}{99}$$

Omil

$$\frac{5 \cdot 13 ^ {2}}{3 ^ {2} \cdot 11} = 8\frac{53}{99} = 8,535353535353535$$
