Yechim qadamlari

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

$$\frac{63+4}{9}+\frac{9\times 6+5}{6}$$

67 olish uchun 63 va 4'ni qo'shing.

$$\frac{67}{9}+\frac{9\times 6+5}{6}$$

54 hosil qilish uchun 9 va 6 ni ko'paytirish.

$$\frac{67}{9}+\frac{54+5}{6}$$

59 olish uchun 54 va 5'ni qo'shing.

$$\frac{67}{9}+\frac{59}{6}$$

9 va 6 ning eng kichik umumiy karralisi 18 ga teng. \frac{67}{9} va \frac{59}{6} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{134}{18}+\frac{177}{18}$$

\frac{134}{18} va \frac{177}{18} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{134+177}{18}$$

311 olish uchun 134 va 177'ni qo'shing.

$$\frac{311}{18}$$

Omil

$$\frac{311}{2 \cdot 3 ^ {2}} = 17\frac{5}{18} = 17,27777777777778$$
