Yechim qadamlari

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

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

5\times \frac{2}{3} ni yagona kasrga aylantiring.

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

10 hosil qilish uchun 5 va 2 ni ko'paytirish.

$$\frac{10}{3}+\frac{2\times 3+1}{3}$$

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

$$\frac{10}{3}+\frac{6+1}{3}$$

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

$$\frac{10}{3}+\frac{7}{3}$$

\frac{10}{3} va \frac{7}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{10+7}{3}$$

17 olish uchun 10 va 7'ni qo'shing.

$$\frac{17}{3}$$

Omil

$$\frac{17}{3} = 5\frac{2}{3} = 5,666666666666667$$
