Yechim qadamlari

5 va 2 ning eng kichik umumiy karralisi 10 ga teng. -\frac{1}{5} va \frac{3}{2} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{2}{10}+\frac{15}{10}-0,3$$

-\frac{2}{10} va \frac{15}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-2+15}{10}-0,3$$

13 olish uchun -2 va 15'ni qo'shing.

$$\frac{13}{10}-0,3$$

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

$$\frac{13}{10}-\frac{3}{10}$$

\frac{13}{10} va \frac{3}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{13-3}{10}$$

10 olish uchun 13 dan 3 ni ayirish.

$$\frac{10}{10}$$

1 ni olish uchun 10 ni 10 ga bo‘ling.
