$$\frac{15}{4}=3,75$$

Yechim qadamlari

\frac{3}{4}\times 3 ni yagona kasrga aylantiring.

$$\frac{3\times 3}{4}+\frac{1\times 2+1}{2}$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{9}{4}+\frac{1\times 2+1}{2}$$

2 hosil qilish uchun 1 va 2 ni ko'paytirish.

$$\frac{9}{4}+\frac{2+1}{2}$$

3 olish uchun 2 va 1'ni qo'shing.

$$\frac{9}{4}+\frac{3}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{9}{4} va \frac{3}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{4}+\frac{6}{4}$$

\frac{9}{4} va \frac{6}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+6}{4}$$

15 olish uchun 9 va 6'ni qo'shing.

$$\frac{15}{4}$$

Omil

$$\frac{3 \cdot 5}{2 ^ {2}} = 3\frac{3}{4} = 3,75$$
