4\left(-\frac{7}{8}\right) ni yagona kasrga aylantiring.

$$\frac{\frac{4\left(-7\right)}{8}}{\frac{1\times 4+3}{4}-\frac{7}{8}-\frac{7}{12}}$$

-28 hosil qilish uchun 4 va -7 ni ko'paytirish.

$$\frac{\frac{-28}{8}}{\frac{1\times 4+3}{4}-\frac{7}{8}-\frac{7}{12}}$$

\frac{-28}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{7}{2}}{\frac{1\times 4+3}{4}-\frac{7}{8}-\frac{7}{12}}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$\frac{-\frac{7}{2}}{\frac{4+3}{4}-\frac{7}{8}-\frac{7}{12}}$$

7 olish uchun 4 va 3'ni qo'shing.

$$\frac{-\frac{7}{2}}{\frac{7}{4}-\frac{7}{8}-\frac{7}{12}}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{7}{4} va \frac{7}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{-\frac{7}{2}}{\frac{14}{8}-\frac{7}{8}-\frac{7}{12}}$$

\frac{14}{8} va \frac{7}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-\frac{7}{2}}{\frac{14-7}{8}-\frac{7}{12}}$$

7 olish uchun 14 dan 7 ni ayirish.

$$\frac{-\frac{7}{2}}{\frac{7}{8}-\frac{7}{12}}$$

8 va 12 ning eng kichik umumiy karralisi 24 ga teng. \frac{7}{8} va \frac{7}{12} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{-\frac{7}{2}}{\frac{21}{24}-\frac{14}{24}}$$

\frac{21}{24} va \frac{14}{24} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-\frac{7}{2}}{\frac{21-14}{24}}$$

7 olish uchun 21 dan 14 ni ayirish.

$$\frac{-\frac{7}{2}}{\frac{7}{24}}$$

-\frac{7}{2} ni \frac{7}{24} ga bo'lish -\frac{7}{2} ga k'paytirish \frac{7}{24} ga qaytarish.

$$-\frac{7}{2}\times \frac{24}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{7}{2} ni \frac{24}{7} ga ko‘paytiring.

$$\frac{-7\times 24}{2\times 7}$$

\frac{-7\times 24}{2\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-168}{14}$$

-12 ni olish uchun -168 ni 14 ga bo‘ling.
