Yechim qadamlari

32 va 3 ning eng kichik umumiy karralisi 96 ga teng. \frac{1}{32} va \frac{1}{3} ni 96 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{96}+\frac{32}{96}+\frac{\frac{1}{21}}{1}$$

\frac{3}{96} va \frac{32}{96} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+32}{96}+\frac{\frac{1}{21}}{1}$$

35 olish uchun 3 va 32'ni qo'shing.

$$\frac{35}{96}+\frac{\frac{1}{21}}{1}$$

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

$$\frac{35}{96}+\frac{1}{21}$$

96 va 21 ning eng kichik umumiy karralisi 672 ga teng. \frac{35}{96} va \frac{1}{21} ni 672 maxraj bilan kasrlarga aylantirib oling.

$$\frac{245}{672}+\frac{32}{672}$$

\frac{245}{672} va \frac{32}{672} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{245+32}{672}$$

277 olish uchun 245 va 32'ni qo'shing.

$$\frac{277}{672}$$

Omil

$$\frac{277}{2 ^ {5} \cdot 3 \cdot 7} = 0,41220238095238093$$
