Yechim qadamlari

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

$$\frac{63+5}{9}+\frac{2\times 3+1}{3}$$

68 olish uchun 63 va 5'ni qo'shing.

$$\frac{68}{9}+\frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{68}{9}+\frac{6+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{68}{9}+\frac{7}{3}$$

9 va 3 ning eng kichik umumiy karralisi 9 ga teng. \frac{68}{9} va \frac{7}{3} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{68}{9}+\frac{21}{9}$$

\frac{68}{9} va \frac{21}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{68+21}{9}$$

89 olish uchun 68 va 21'ni qo'shing.

$$\frac{89}{9}$$

Omil

$$\frac{89}{3 ^ {2}} = 9\frac{8}{9} = 9,88888888888889$$
