Yechim qadamlari

2 va 6 ning eng kichik umumiy karralisi 6 ga teng. -\frac{1}{2} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{3}{6}+\frac{5}{6}-\frac{2}{9}$$

-\frac{3}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3+5}{6}-\frac{2}{9}$$

2 olish uchun -3 va 5'ni qo'shing.

$$\frac{2}{6}-\frac{2}{9}$$

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

$$\frac{1}{3}-\frac{2}{9}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{1}{3} va \frac{2}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{9}-\frac{2}{9}$$

\frac{3}{9} va \frac{2}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-2}{9}$$

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{1}{9}$$

Omil

$$\frac{1}{3 ^ {2}} = 0,1111111111111111$$
