Yechim qadamlari

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

$$\frac{-\frac{15+3}{5}}{-\frac{4\times 3+2}{3}}$$

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

$$\frac{-\frac{18}{5}}{-\frac{4\times 3+2}{3}}$$

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$\frac{-\frac{18}{5}}{-\frac{12+2}{3}}$$

14 olish uchun 12 va 2'ni qo'shing.

$$\frac{-\frac{18}{5}}{-\frac{14}{3}}$$

-\frac{18}{5} ni -\frac{14}{3} ga bo'lish -\frac{18}{5} ga k'paytirish -\frac{14}{3} ga qaytarish.

$$-\frac{18}{5}\left(-\frac{3}{14}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{18}{5} ni -\frac{3}{14} ga ko‘paytiring.

$$\frac{-18\left(-3\right)}{5\times 14}$$

\frac{-18\left(-3\right)}{5\times 14} kasridagi ko‘paytirishlarni bajaring.

$$\frac{54}{70}$$

\frac{54}{70} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
