Yechim qadamlari

-2 ni -\frac{6}{3} kasrga o‘giring.

$$-\frac{6}{3}+\frac{2}{3}-\frac{1}{2}$$

-\frac{6}{3} va \frac{2}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-6+2}{3}-\frac{1}{2}$$

-4 olish uchun -6 va 2'ni qo'shing.

$$-\frac{4}{3}-\frac{1}{2}$$

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. -\frac{4}{3} va \frac{1}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{8}{6}-\frac{3}{6}$$

-\frac{8}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-8-3}{6}$$

-11 olish uchun -8 dan 3 ni ayirish.

$$-\frac{11}{6}$$

Omil

$$-\frac{11}{6} = -1\frac{5}{6} = -1,8333333333333333$$
