3+1/2-3/4 eching

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

Baholash

$$\frac{11}{4}=2,75$$

Yechim qadamlari

3 ni \frac{6}{2} kasrga o‘giring.

$$\frac{6}{2}+\frac{1}{2}-\frac{3}{4}$$

\frac{6}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+1}{2}-\frac{3}{4}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{7}{2}-\frac{3}{4}$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{7}{2} va \frac{3}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{14}{4}-\frac{3}{4}$$

\frac{14}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{14-3}{4}$$

11 olish uchun 14 dan 3 ni ayirish.

$$\frac{11}{4}$$

Omil

$$\frac{11}{2 ^ {2}} = 2\frac{3}{4} = 2,75$$
