Yechim qadamlari

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

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

11 olish uchun 8 va 3'ni qo'shing.

$$\frac{11}{4}-\frac{2\times 2+1}{2}$$

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

$$\frac{11}{4}-\frac{4+1}{2}$$

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

$$\frac{11}{4}-\frac{5}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{11}{4} va \frac{5}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{11}{4}-\frac{10}{4}$$

\frac{11}{4} va \frac{10}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{11-10}{4}$$

1 olish uchun 11 dan 10 ni ayirish.

$$\frac{1}{4}$$
