Yechim qadamlari

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\left(-\frac{15+3}{5}\right)\left(\frac{2}{3}-275\right)$$

18 olish uchun 15 va 3'ni qo'shing.

$$-\frac{18}{5}\left(\frac{2}{3}-275\right)$$

275 ni \frac{825}{3} kasrga o‘giring.

$$-\frac{18}{5}\left(\frac{2}{3}-\frac{825}{3}\right)$$

\frac{2}{3} va \frac{825}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-\frac{18}{5}\times \frac{2-825}{3}$$

-823 olish uchun 2 dan 825 ni ayirish.

$$-\frac{18}{5}\left(-\frac{823}{3}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{18}{5} ni -\frac{823}{3} ga ko‘paytiring.

$$\frac{-18\left(-823\right)}{5\times 3}$$

\frac{-18\left(-823\right)}{5\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{14814}{15}$$

\frac{14814}{15} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{4938}{5}$$

Omil

$$\frac{2 \cdot 3 \cdot 823}{5} = 987\frac{3}{5} = 987,6$$
