Yechim qadamlari

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{6+2}{3}-\frac{8}{9}\left(-\frac{5+3}{5}\right)$$

8 olish uchun 6 va 2'ni qo'shing.

$$\frac{8}{3}-\frac{8}{9}\left(-\frac{5+3}{5}\right)$$

8 olish uchun 5 va 3'ni qo'shing.

$$\frac{8}{3}-\frac{8}{9}\left(-\frac{8}{5}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{8}{9} ni -\frac{8}{5} ga ko‘paytiring.

$$\frac{8}{3}+\frac{-8\left(-8\right)}{9\times 5}$$

\frac{-8\left(-8\right)}{9\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{8}{3}+\frac{64}{45}$$

3 va 45 ning eng kichik umumiy karralisi 45 ga teng. \frac{8}{3} va \frac{64}{45} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{120}{45}+\frac{64}{45}$$

\frac{120}{45} va \frac{64}{45} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{120+64}{45}$$

184 olish uchun 120 va 64'ni qo'shing.

$$\frac{184}{45}$$
