Yechim qadamlari

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{8} va \frac{1}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{8}+\frac{4}{8}-\frac{1}{16}$$

\frac{3}{8} va \frac{4}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+4}{8}-\frac{1}{16}$$

7 olish uchun 3 va 4'ni qo'shing.

$$\frac{7}{8}-\frac{1}{16}$$

8 va 16 ning eng kichik umumiy karralisi 16 ga teng. \frac{7}{8} va \frac{1}{16} ni 16 maxraj bilan kasrlarga aylantirib oling.

$$\frac{14}{16}-\frac{1}{16}$$

\frac{14}{16} va \frac{1}{16} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{14-1}{16}$$

13 olish uchun 14 dan 1 ni ayirish.

$$\frac{13}{16}$$
