Yechim qadamlari

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{2}{3} va \frac{8}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{9}+\frac{8}{9}+\frac{3}{5}$$

\frac{6}{9} va \frac{8}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+8}{9}+\frac{3}{5}$$

14 olish uchun 6 va 8'ni qo'shing.

$$\frac{14}{9}+\frac{3}{5}$$

9 va 5 ning eng kichik umumiy karralisi 45 ga teng. \frac{14}{9} va \frac{3}{5} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{70}{45}+\frac{27}{45}$$

\frac{70}{45} va \frac{27}{45} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{70+27}{45}$$

97 olish uchun 70 va 27'ni qo'shing.

$$\frac{97}{45}$$

Omil

$$\frac{97}{3 ^ {2} \cdot 5} = 2\frac{7}{45} = 2,1555555555555554$$
