Yechim qadamlari

8 va 12 ning eng kichik umumiy karralisi 24 ga teng. \frac{3}{8} va \frac{5}{12} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{24}+\frac{10}{24}+\frac{5}{32}$$

\frac{9}{24} va \frac{10}{24} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+10}{24}+\frac{5}{32}$$

19 olish uchun 9 va 10'ni qo'shing.

$$\frac{19}{24}+\frac{5}{32}$$

24 va 32 ning eng kichik umumiy karralisi 96 ga teng. \frac{19}{24} va \frac{5}{32} ni 96 maxraj bilan kasrlarga aylantirib oling.

$$\frac{76}{96}+\frac{15}{96}$$

\frac{76}{96} va \frac{15}{96} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{76+15}{96}$$

91 olish uchun 76 va 15'ni qo'shing.

$$\frac{91}{96}$$
