Yechim qadamlari

2 va 6 ning eng kichik umumiy karralisi 6 ga teng. \frac{3}{2} va \frac{5}{6} ni 6 maxraj bilan kasrlarga aylantirib oling.

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

\frac{9}{6} va \frac{5}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

4 olish uchun 9 dan 5 ni ayirish.

$$\frac{4}{6}-\frac{2}{9}$$

\frac{4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

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

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

\frac{6}{9} va \frac{2}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

4 olish uchun 6 dan 2 ni ayirish.

$$\frac{4}{9}$$
