Yechim qadamlari

5\left(-\frac{2}{3}\right) ni yagona kasrga aylantiring.

$$\frac{5\left(-2\right)}{3}+18$$

-10 hosil qilish uchun 5 va -2 ni ko'paytirish.

$$\frac{-10}{3}+18$$

\frac{-10}{3} kasri manfiy belgini olib tashlash bilan -\frac{10}{3} sifatida qayta yozilishi mumkin.

$$-\frac{10}{3}+18$$

18 ni \frac{54}{3} kasrga o‘giring.

$$-\frac{10}{3}+\frac{54}{3}$$

-\frac{10}{3} va \frac{54}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-10+54}{3}$$

44 olish uchun -10 va 54'ni qo'shing.

$$\frac{44}{3}$$

Omil

$$\frac{2 ^ {2} \cdot 11}{3} = 14\frac{2}{3} = 14,666666666666666$$
