Yechim qadamlari

1 ni olish uchun 9 ni 9 ga bo‘ling.

$$1\times 6-\frac{8\times 9}{5}+6\times 9$$

6 hosil qilish uchun 1 va 6 ni ko'paytirish. 54 hosil qilish uchun 6 va 9 ni ko'paytirish.

$$6-\frac{8\times 9}{5}+54$$

72 hosil qilish uchun 8 va 9 ni ko'paytirish.

$$6-\frac{72}{5}+54$$

6 ni \frac{30}{5} kasrga o‘giring.

$$\frac{30}{5}-\frac{72}{5}+54$$

\frac{30}{5} va \frac{72}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{30-72}{5}+54$$

-42 olish uchun 30 dan 72 ni ayirish.

$$-\frac{42}{5}+54$$

54 ni \frac{270}{5} kasrga o‘giring.

$$-\frac{42}{5}+\frac{270}{5}$$

-\frac{42}{5} va \frac{270}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-42+270}{5}$$

228 olish uchun -42 va 270'ni qo'shing.

$$\frac{228}{5}$$
