Yechim qadamlari

\frac{-3}{2} kasri manfiy belgini olib tashlash bilan -\frac{3}{2} sifatida qayta yozilishi mumkin.

$$1-\frac{3}{2}-\frac{5}{-3}$$

1 ni \frac{2}{2} kasrga o‘giring.

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

\frac{2}{2} va \frac{3}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-1 olish uchun 2 dan 3 ni ayirish.

$$-\frac{1}{2}-\frac{5}{-3}$$

\frac{5}{-3} kasri manfiy belgini olib tashlash bilan -\frac{5}{3} sifatida qayta yozilishi mumkin.

$$-\frac{1}{2}-\left(-\frac{5}{3}\right)$$

-\frac{5}{3} ning teskarisi \frac{5}{3} ga teng.

$$-\frac{1}{2}+\frac{5}{3}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. -\frac{1}{2} va \frac{5}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{3}{6}+\frac{10}{6}$$

-\frac{3}{6} va \frac{10}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3+10}{6}$$

7 olish uchun -3 va 10'ni qo'shing.

$$\frac{7}{6}$$

Omil

$$\frac{7}{2 \cdot 3} = 1\frac{1}{6} = 1,1666666666666667$$
