Yechim qadamlari

-\frac{3}{4} ning teskarisi \frac{3}{4} ga teng.

$$\frac{3}{2}+\frac{3}{4}-\frac{1}{2}-\left(-\frac{5}{4}\right)$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{3}{2} va \frac{3}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{4}+\frac{3}{4}-\frac{1}{2}-\left(-\frac{5}{4}\right)$$

\frac{6}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+3}{4}-\frac{1}{2}-\left(-\frac{5}{4}\right)$$

9 olish uchun 6 va 3'ni qo'shing.

$$\frac{9}{4}-\frac{1}{2}-\left(-\frac{5}{4}\right)$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{9}{4} va \frac{1}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{4}-\frac{2}{4}-\left(-\frac{5}{4}\right)$$

\frac{9}{4} va \frac{2}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-2}{4}-\left(-\frac{5}{4}\right)$$

7 olish uchun 9 dan 2 ni ayirish.

$$\frac{7}{4}-\left(-\frac{5}{4}\right)$$

-\frac{5}{4} ning teskarisi \frac{5}{4} ga teng.

$$\frac{7}{4}+\frac{5}{4}$$

\frac{7}{4} va \frac{5}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7+5}{4}$$

12 olish uchun 7 va 5'ni qo'shing.

$$\frac{12}{4}$$

3 ni olish uchun 12 ni 4 ga bo‘ling.
