Yechim qadamlari

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$\frac{\frac{1}{2}\times 2-\frac{1}{3}}{3+\frac{\frac{2}{3}}{\frac{1}{3}}}$$

2 va 2 ni qisqartiring.

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

1 ni \frac{3}{3} kasrga o‘giring.

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

\frac{3}{3} va \frac{1}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

2 olish uchun 3 dan 1 ni ayirish.

$$\frac{\frac{2}{3}}{3+\frac{\frac{2}{3}}{\frac{1}{3}}}$$

\frac{2}{3} ni \frac{1}{3} ga bo'lish \frac{2}{3} ga k'paytirish \frac{1}{3} ga qaytarish.

$$\frac{\frac{2}{3}}{3+\frac{2}{3}\times 3}$$

3 va 3 ni qisqartiring.

$$\frac{\frac{2}{3}}{3+2}$$

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

$$\frac{\frac{2}{3}}{5}$$

\frac{\frac{2}{3}}{5} ni yagona kasrga aylantiring.

$$\frac{2}{3\times 5}$$

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\frac{2}{15}$$

Omil

$$\frac{2}{3 \cdot 5} = 0,13333333333333333$$
