Yechim qadamlari

2 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{1}{2} va \frac{1}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2}{\frac{4}{8}+\frac{1}{8}}$$

\frac{4}{8} va \frac{1}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2}{\frac{4+1}{8}}$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{2}{\frac{5}{8}}$$

2 ni \frac{5}{8} ga bo'lish 2 ga k'paytirish \frac{5}{8} ga qaytarish.

$$2\times \frac{8}{5}$$

2\times \frac{8}{5} ni yagona kasrga aylantiring.

$$\frac{2\times 8}{5}$$

16 hosil qilish uchun 2 va 8 ni ko'paytirish.

$$\frac{16}{5}$$

Omil

$$\frac{2 ^ {4}}{5} = 3\frac{1}{5} = 3,2$$
