Yechim qadamlari

\frac{-2}{7} kasri manfiy belgini olib tashlash bilan -\frac{2}{7} sifatida qayta yozilishi mumkin.

$$-\frac{2}{7}+\frac{1}{3}\times \frac{6}{11}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{3} ni \frac{6}{11} ga ko‘paytiring.

$$-\frac{2}{7}+\frac{1\times 6}{3\times 11}$$

\frac{1\times 6}{3\times 11} kasridagi ko‘paytirishlarni bajaring.

$$-\frac{2}{7}+\frac{6}{33}$$

\frac{6}{33} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{2}{7}+\frac{2}{11}$$

7 va 11 ning eng kichik umumiy karralisi 77 ga teng. -\frac{2}{7} va \frac{2}{11} ni 77 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{22}{77}+\frac{14}{77}$$

-\frac{22}{77} va \frac{14}{77} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-22+14}{77}$$

-8 olish uchun -22 va 14'ni qo'shing.

$$-\frac{8}{77}$$
