Yechim qadamlari

8 va 4 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{8} va \frac{7}{4} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{8}-\frac{14}{8}+\frac{2}{161}$$

\frac{3}{8} va \frac{14}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-14}{8}+\frac{2}{161}$$

-11 olish uchun 3 dan 14 ni ayirish.

$$-\frac{11}{8}+\frac{2}{161}$$

8 va 161 ning eng kichik umumiy karralisi 1288 ga teng. -\frac{11}{8} va \frac{2}{161} ni 1288 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1771}{1288}+\frac{16}{1288}$$

-\frac{1771}{1288} va \frac{16}{1288} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1771+16}{1288}$$

-1755 olish uchun -1771 va 16'ni qo'shing.

$$-\frac{1755}{1288}$$
