2 ni \frac{16}{8} kasrga o‘giring.

$$\frac{21}{8}+\frac{16}{8}-12\times 3=2$$

\frac{21}{8} va \frac{16}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{21+16}{8}-12\times 3=2$$

37 olish uchun 21 va 16'ni qo'shing.

$$\frac{37}{8}-12\times 3=2$$

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

$$\frac{37}{8}-36=2$$

36 ni \frac{288}{8} kasrga o‘giring.

$$\frac{37}{8}-\frac{288}{8}=2$$

\frac{37}{8} va \frac{288}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{37-288}{8}=2$$

-251 olish uchun 37 dan 288 ni ayirish.

$$-\frac{251}{8}=2$$

2 ni \frac{16}{8} kasrga o‘giring.

$$-\frac{251}{8}=\frac{16}{8}$$

-\frac{251}{8} va \frac{16}{8} ni taqqoslang.
