$$63+\frac{26}{21}-2$$

63 ni \frac{1323}{21} kasrga o‘giring.

$$\frac{1323}{21}+\frac{26}{21}-2$$

\frac{1323}{21} va \frac{26}{21} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1323+26}{21}-2$$

1349 olish uchun 1323 va 26'ni qo'shing.

$$\frac{1349}{21}-2$$

2 ni \frac{42}{21} kasrga o‘giring.

$$\frac{1349}{21}-\frac{42}{21}$$

\frac{1349}{21} va \frac{42}{21} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1349-42}{21}$$

1307 olish uchun 1349 dan 42 ni ayirish.

$$\frac{1307}{21}$$

Omil

$$\frac{1307}{3 \cdot 7} = 62\frac{5}{21} = 62,23809523809524$$
