Yechim qadamlari

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{2}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

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

\frac{3}{6} va \frac{4}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-1 olish uchun 3 dan 4 ni ayirish.

$$-\frac{1}{6}-\left(-\frac{1\times 6+1}{6}\right)$$

6 hosil qilish uchun 1 va 6 ni ko'paytirish.

$$-\frac{1}{6}-\left(-\frac{6+1}{6}\right)$$

7 olish uchun 6 va 1'ni qo'shing.

$$-\frac{1}{6}-\left(-\frac{7}{6}\right)$$

-\frac{7}{6} ning teskarisi \frac{7}{6} ga teng.

$$-\frac{1}{6}+\frac{7}{6}$$

-\frac{1}{6} va \frac{7}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1+7}{6}$$

6 olish uchun -1 va 7'ni qo'shing.

$$\frac{6}{6}$$

1 ni olish uchun 6 ni 6 ga bo‘ling.
