Yechim qadamlari

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

$$\frac{3}{8}+\frac{2+1}{2}+\frac{1\times 4+1}{4}$$

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

$$\frac{3}{8}+\frac{3}{2}+\frac{1\times 4+1}{4}$$

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{8} va \frac{3}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{8}+\frac{12}{8}+\frac{1\times 4+1}{4}$$

\frac{3}{8} va \frac{12}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+12}{8}+\frac{1\times 4+1}{4}$$

15 olish uchun 3 va 12'ni qo'shing.

$$\frac{15}{8}+\frac{1\times 4+1}{4}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.
