Yechim qadamlari

1 ni \frac{5}{5} kasrga o‘giring.

$$\frac{3}{\frac{5}{5}-\frac{2}{5}}\left(2-\frac{9}{5}\right)$$

\frac{5}{5} va \frac{2}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3}{\frac{5-2}{5}}\left(2-\frac{9}{5}\right)$$

3 olish uchun 5 dan 2 ni ayirish.

$$\frac{3}{\frac{3}{5}}\left(2-\frac{9}{5}\right)$$

3 ni \frac{3}{5} ga bo'lish 3 ga k'paytirish \frac{3}{5} ga qaytarish.

$$3\times \frac{5}{3}\left(2-\frac{9}{5}\right)$$

3 va 3 ni qisqartiring.

$$5\left(2-\frac{9}{5}\right)$$

2 ni \frac{10}{5} kasrga o‘giring.

$$5\left(\frac{10}{5}-\frac{9}{5}\right)$$

\frac{10}{5} va \frac{9}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$5\times \frac{10-9}{5}$$

1 olish uchun 10 dan 9 ni ayirish.

$$5\times \frac{1}{5}$$

5 va 5 ni qisqartiring.
