1/2+1/4-3/8= eching

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

Baholash

$$\frac{3}{8}=0,375$$

Yechim qadamlari

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{1}{2} va \frac{1}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

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

\frac{2}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

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

$$\frac{3}{4}-\frac{3}{8}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{4} va \frac{3}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{8}-\frac{3}{8}$$

\frac{6}{8} va \frac{3}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-3}{8}$$

3 olish uchun 6 dan 3 ni ayirish.

$$\frac{3}{8}$$

Omil

$$\frac{3}{2 ^ {3}} = 0,375$$
