Yechim qadamlari

-\frac{1}{9} ning teskarisi \frac{1}{9} ga teng.

$$\frac{1}{5}+\frac{1}{9}-\frac{5}{9}-0\times 2$$

5 va 9 ning eng kichik umumiy karralisi 45 ga teng. \frac{1}{5} va \frac{1}{9} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{45}+\frac{5}{45}-\frac{5}{9}-0\times 2$$

\frac{9}{45} va \frac{5}{45} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+5}{45}-\frac{5}{9}-0\times 2$$

14 olish uchun 9 va 5'ni qo'shing.

$$\frac{14}{45}-\frac{5}{9}-0\times 2$$

45 va 9 ning eng kichik umumiy karralisi 45 ga teng. \frac{14}{45} va \frac{5}{9} ni 45 maxraj bilan kasrlarga aylantirib oling.

$$\frac{14}{45}-\frac{25}{45}-0\times 2$$

\frac{14}{45} va \frac{25}{45} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{14-25}{45}-0\times 2$$

-11 olish uchun 14 dan 25 ni ayirish.
