Yechim qadamlari

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

$$\frac{1}{5}-2\left(\frac{3}{2}-1\right)+0,3$$

1 ni \frac{2}{2} kasrga o‘giring.

$$\frac{1}{5}-2\left(\frac{3}{2}-\frac{2}{2}\right)+0,3$$

\frac{3}{2} va \frac{2}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1}{5}-2\times \frac{3-2}{2}+0,3$$

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{1}{5}-2\times \frac{1}{2}+0,3$$

2 va 2 ni qisqartiring.

$$\frac{1}{5}-1+0,3$$

1 ni \frac{5}{5} kasrga o‘giring.

$$\frac{1}{5}-\frac{5}{5}+0,3$$

\frac{1}{5} va \frac{5}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-5}{5}+0,3$$

-4 olish uchun 1 dan 5 ni ayirish.

$$-\frac{4}{5}+0,3$$

0,3 o‘nlik raqamni uning \frac{3}{10} kasrga o‘giring.

$$-\frac{4}{5}+\frac{3}{10}$$

5 va 10 ning eng kichik umumiy karralisi 10 ga teng. -\frac{4}{5} va \frac{3}{10} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{8}{10}+\frac{3}{10}$$

-\frac{8}{10} va \frac{3}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-8+3}{10}$$

-5 olish uchun -8 va 3'ni qo'shing.

$$\frac{-5}{10}$$

\frac{-5}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{2}$$
