Yechim qadamlari

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

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

1 ni \frac{2}{2} kasrga o‘giring.

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

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

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

-1 olish uchun 2 dan 3 ni ayirish.

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

-6 hosil qilish uchun 2 va -3 ni ko'paytirish.

$$-\frac{1}{2}-\frac{-6+5}{-3}$$

-1 olish uchun -6 va 5'ni qo'shing.

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

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-1}{-3} kasrini \frac{1}{3} ga soddalashtirish mumkin.

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

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

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

-\frac{3}{6} va \frac{2}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-5 olish uchun -3 dan 2 ni ayirish.

$$-\frac{5}{6}$$
