Yechim qadamlari

\frac{1\times 3+2}{3} ni -\frac{3}{7} ga bo'lish \frac{1\times 3+2}{3} ga k'paytirish -\frac{3}{7} ga qaytarish.

$$-\frac{5}{6}+\frac{\left(1\times 3+2\right)\times 7}{3\left(-3\right)}$$

3 hosil qilish uchun 1 va 3 ni ko'paytirish.

$$-\frac{5}{6}+\frac{\left(3+2\right)\times 7}{3\left(-3\right)}$$

5 olish uchun 3 va 2'ni qo'shing.

$$-\frac{5}{6}+\frac{5\times 7}{3\left(-3\right)}$$

35 hosil qilish uchun 5 va 7 ni ko'paytirish.

$$-\frac{5}{6}+\frac{35}{3\left(-3\right)}$$

-9 hosil qilish uchun 3 va -3 ni ko'paytirish.

$$-\frac{5}{6}+\frac{35}{-9}$$

\frac{35}{-9} kasri manfiy belgini olib tashlash bilan -\frac{35}{9} sifatida qayta yozilishi mumkin.

$$-\frac{5}{6}-\frac{35}{9}$$

6 va 9 ning eng kichik umumiy karralisi 18 ga teng. -\frac{5}{6} va \frac{35}{9} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{15}{18}-\frac{70}{18}$$

-\frac{15}{18} va \frac{70}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-15-70}{18}$$

-85 olish uchun -15 dan 70 ni ayirish.

$$-\frac{85}{18}$$

Omil

$$-\frac{85}{18} = -4\frac{13}{18} = -4,722222222222222$$
