$$\frac{8}{20}-\frac{25}{20}+45+\frac{25}{100}$$

\frac{8}{20} va \frac{25}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{8-25}{20}+45+\frac{25}{100}$$

-17 olish uchun 8 dan 25 ni ayirish.

$$-\frac{17}{20}+45+\frac{25}{100}$$

45 ni \frac{900}{20} kasrga o‘giring.

$$-\frac{17}{20}+\frac{900}{20}+\frac{25}{100}$$

-\frac{17}{20} va \frac{900}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
