Yechim qadamlari

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

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

-\frac{4}{6} va \frac{1}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-5 olish uchun -4 dan 1 ni ayirish.

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

-\frac{1}{4} ning teskarisi \frac{1}{4} ga teng.

$$-\frac{5}{6}+\frac{1}{4}-\frac{1}{2}$$

6 va 4 ning eng kichik umumiy karralisi 12 ga teng. -\frac{5}{6} va \frac{1}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{10}{12}+\frac{3}{12}-\frac{1}{2}$$

-\frac{10}{12} va \frac{3}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-10+3}{12}-\frac{1}{2}$$

-7 olish uchun -10 va 3'ni qo'shing.

$$-\frac{7}{12}-\frac{1}{2}$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. -\frac{7}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{7}{12}-\frac{6}{12}$$

-\frac{7}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-7-6}{12}$$

-13 olish uchun -7 dan 6 ni ayirish.

$$-\frac{13}{12}$$
