1/2+23/4-3/8 eching

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

Baholash

$$\frac{23}{8}=2,875$$

Yechim qadamlari

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

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

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

$$\frac{1}{2}+\frac{11}{4}-\frac{3}{8}$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{1}{2} va \frac{11}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2}{4}+\frac{11}{4}-\frac{3}{8}$$

\frac{2}{4} va \frac{11}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2+11}{4}-\frac{3}{8}$$

13 olish uchun 2 va 11'ni qo'shing.

$$\frac{13}{4}-\frac{3}{8}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{13}{4} va \frac{3}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{26}{8}-\frac{3}{8}$$

\frac{26}{8} va \frac{3}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{26-3}{8}$$

23 olish uchun 26 dan 3 ni ayirish.

$$\frac{23}{8}$$

Omil

$$\frac{23}{2 ^ {3}} = 2\frac{7}{8} = 2,875$$
