$$\frac{59}{10}=5,9$$

Yechim qadamlari

2 hosil qilish uchun 1 va 2 ni ko'paytirish.

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

5 olish uchun 2 va 3'ni qo'shing.

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

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\frac{5}{2}+\frac{15+2}{5}$$

17 olish uchun 15 va 2'ni qo'shing.

$$\frac{5}{2}+\frac{17}{5}$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{5}{2} va \frac{17}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{25}{10}+\frac{34}{10}$$

\frac{25}{10} va \frac{34}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{25+34}{10}$$

59 olish uchun 25 va 34'ni qo'shing.

$$\frac{59}{10}$$

Omil

$$\frac{59}{2 \cdot 5} = 5\frac{9}{10} = 5,9$$
