Yechim qadamlari

-5 ni -\frac{10}{2} kasrga o‘giring.

$$-\frac{10}{2}+\frac{1}{2}+7-\frac{7}{3}$$

-\frac{10}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-10+1}{2}+7-\frac{7}{3}$$

-9 olish uchun -10 va 1'ni qo'shing.

$$-\frac{9}{2}+7-\frac{7}{3}$$

7 ni \frac{14}{2} kasrga o‘giring.

$$-\frac{9}{2}+\frac{14}{2}-\frac{7}{3}$$

-\frac{9}{2} va \frac{14}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-9+14}{2}-\frac{7}{3}$$

5 olish uchun -9 va 14'ni qo'shing.

$$\frac{5}{2}-\frac{7}{3}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{5}{2} va \frac{7}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{15}{6}-\frac{14}{6}$$

\frac{15}{6} va \frac{14}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{15-14}{6}$$

1 olish uchun 15 dan 14 ni ayirish.

$$\frac{1}{6}$$
