Yechim qadamlari

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

$$\frac{3}{\frac{6}{7}-2}$$

2 ni \frac{14}{7} kasrga o‘giring.

$$\frac{3}{\frac{6}{7}-\frac{14}{7}}$$

\frac{6}{7} va \frac{14}{7} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3}{\frac{6-14}{7}}$$

-8 olish uchun 6 dan 14 ni ayirish.

$$\frac{3}{-\frac{8}{7}}$$

3 ni -\frac{8}{7} ga bo'lish 3 ga k'paytirish -\frac{8}{7} ga qaytarish.

$$3\left(-\frac{7}{8}\right)$$

3\left(-\frac{7}{8}\right) ni yagona kasrga aylantiring.

$$\frac{3\left(-7\right)}{8}$$

-21 hosil qilish uchun 3 va -7 ni ko'paytirish.

$$\frac{-21}{8}$$

\frac{-21}{8} kasri manfiy belgini olib tashlash bilan -\frac{21}{8} sifatida qayta yozilishi mumkin.

$$-\frac{21}{8}$$

Omil

$$-\frac{21}{8} = -2\frac{5}{8} = -2,625$$
