23/4-7/8= eching

$$2 \frac { 3 } { 4 } - \frac { 7 } { 8 } =$$

Baholash

$$\frac{15}{8}=1,875$$

Yechim qadamlari

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

$$\frac{8+3}{4}-\frac{7}{8}$$

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

$$\frac{11}{4}-\frac{7}{8}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{11}{4} va \frac{7}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{22}{8}-\frac{7}{8}$$

\frac{22}{8} va \frac{7}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{22-7}{8}$$

15 olish uchun 22 dan 7 ni ayirish.

$$\frac{15}{8}$$

Omil

$$\frac{3 \cdot 5}{2 ^ {3}} = 1\frac{7}{8} = 1,875$$
