Yechim qadamlari

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

$$\frac{3}{6}-\frac{4}{6}-\frac{1\times 6+1}{6}$$

\frac{3}{6} va \frac{4}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-4}{6}-\frac{1\times 6+1}{6}$$

-1 olish uchun 3 dan 4 ni ayirish.

$$-\frac{1}{6}-\frac{1\times 6+1}{6}$$

6 hosil qilish uchun 1 va 6 ni ko'paytirish.

$$-\frac{1}{6}-\frac{6+1}{6}$$

7 olish uchun 6 va 1'ni qo'shing.

$$-\frac{1}{6}-\frac{7}{6}$$

-\frac{1}{6} va \frac{7}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-1-7}{6}$$

-8 olish uchun -1 dan 7 ni ayirish.

$$\frac{-8}{6}$$

\frac{-8}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

Omil

$$-\frac{4}{3} = -1\frac{1}{3} = -1,3333333333333333$$
