$$\frac{100}{500}+\frac{3}{500}+\frac{1}{2000}-\frac{5}{1}$$

\frac{100}{500} va \frac{3}{500} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{100+3}{500}+\frac{1}{2000}-\frac{5}{1}$$

103 olish uchun 100 va 3'ni qo'shing.

$$\frac{103}{500}+\frac{1}{2000}-\frac{5}{1}$$

500 va 2000 ning eng kichik umumiy karralisi 2000 ga teng. \frac{103}{500} va \frac{1}{2000} ni 2000 maxraj bilan kasrlarga aylantirib oling.

$$\frac{412}{2000}+\frac{1}{2000}-\frac{5}{1}$$

\frac{412}{2000} va \frac{1}{2000} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{412+1}{2000}-\frac{5}{1}$$

413 olish uchun 412 va 1'ni qo'shing.

$$\frac{413}{2000}-\frac{5}{1}$$

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

$$\frac{413}{2000}-5$$

5 ni \frac{10000}{2000} kasrga o‘giring.

$$\frac{413}{2000}-\frac{10000}{2000}$$

\frac{413}{2000} va \frac{10000}{2000} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{413-10000}{2000}$$

-9587 olish uchun 413 dan 10000 ni ayirish.

$$-\frac{9587}{2000}$$

Omil

$$-\frac{9587}{2000} = -4\frac{1587}{2000} = -4,7935$$
