Yechim qadamlari

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$-\frac{8+1}{4}-\frac{4\times 3+1}{3}$$

9 olish uchun 8 va 1'ni qo'shing.

$$-\frac{9}{4}-\frac{4\times 3+1}{3}$$

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$-\frac{9}{4}-\frac{12+1}{3}$$

13 olish uchun 12 va 1'ni qo'shing.

$$-\frac{9}{4}-\frac{13}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. -\frac{9}{4} va \frac{13}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{27}{12}-\frac{52}{12}$$

-\frac{27}{12} va \frac{52}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-27-52}{12}$$

-79 olish uchun -27 dan 52 ni ayirish.

$$-\frac{79}{12}$$

Omil

$$-\frac{79}{12} = -6\frac{7}{12} = -6,583333333333333$$
