Yechim qadamlari

\frac{-45}{11} kasri manfiy belgini olib tashlash bilan -\frac{45}{11} sifatida qayta yozilishi mumkin.

$$\frac{7}{5}\left(-\frac{45}{11}\right)-\frac{6}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{5} ni -\frac{45}{11} ga ko‘paytiring.

$$\frac{7\left(-45\right)}{5\times 11}-\frac{6}{5}$$

\frac{7\left(-45\right)}{5\times 11} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-315}{55}-\frac{6}{5}$$

\frac{-315}{55} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{63}{11}-\frac{6}{5}$$

11 va 5 ning eng kichik umumiy karralisi 55 ga teng. -\frac{63}{11} va \frac{6}{5} ni 55 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{315}{55}-\frac{66}{55}$$

-\frac{315}{55} va \frac{66}{55} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-315-66}{55}$$

-381 olish uchun -315 dan 66 ni ayirish.

$$-\frac{381}{55}$$
