Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{5}{6} ni \frac{4}{15} ga ko‘paytiring.

$$\frac{\frac{-5\times 4}{6\times 15}-\frac{2}{15}}{-8}$$

\frac{-5\times 4}{6\times 15} kasridagi ko‘paytirishlarni bajaring.

$$\frac{\frac{-20}{90}-\frac{2}{15}}{-8}$$

\frac{-20}{90} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{2}{9}-\frac{2}{15}}{-8}$$

9 va 15 ning eng kichik umumiy karralisi 45 ga teng. -\frac{2}{9} va \frac{2}{15} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{-\frac{10}{45}-\frac{6}{45}}{-8}$$

-\frac{10}{45} va \frac{6}{45} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{-10-6}{45}}{-8}$$

-16 olish uchun -10 dan 6 ni ayirish.

$$\frac{-\frac{16}{45}}{-8}$$

\frac{-\frac{16}{45}}{-8} ni yagona kasrga aylantiring.

$$\frac{-16}{45\left(-8\right)}$$

-360 hosil qilish uchun 45 va -8 ni ko'paytirish.

$$\frac{-16}{-360}$$

\frac{-16}{-360} ulushini -8 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{2}{45}$$
