Yechim qadamlari

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

$$\frac{15+2}{3}-\frac{1\times 5+1}{5}-\frac{2\times 3+1}{3}$$

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

$$\frac{17}{3}-\frac{1\times 5+1}{5}-\frac{2\times 3+1}{3}$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{17}{3}-\frac{5+1}{5}-\frac{2\times 3+1}{3}$$

6 olish uchun 5 va 1'ni qo'shing.

$$\frac{17}{3}-\frac{6}{5}-\frac{2\times 3+1}{3}$$

3 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{17}{3} va \frac{6}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{85}{15}-\frac{18}{15}-\frac{2\times 3+1}{3}$$

\frac{85}{15} va \frac{18}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{85-18}{15}-\frac{2\times 3+1}{3}$$

67 olish uchun 85 dan 18 ni ayirish.

$$\frac{67}{15}-\frac{2\times 3+1}{3}$$

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

$$\frac{67}{15}-\frac{6+1}{3}$$

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

$$\frac{67}{15}-\frac{7}{3}$$

15 va 3 ning eng kichik umumiy karralisi 15 ga teng. \frac{67}{15} va \frac{7}{3} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{67}{15}-\frac{35}{15}$$

\frac{67}{15} va \frac{35}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{67-35}{15}$$

32 olish uchun 67 dan 35 ni ayirish.

$$\frac{32}{15}$$

Omil

$$\frac{2 ^ {5}}{3 \cdot 5} = 2\frac{2}{15} = 2,1333333333333333$$
