63/4-7/8 eching

$$6 \frac { 3 } { 4 } - \frac { 7 } { 8 }$$

Baholash

$$\frac{47}{8}=5,875$$

Yechim qadamlari

24 hosil qilish uchun 6 va 4 ni ko'paytirish.

$$\frac{24+3}{4}-\frac{7}{8}$$

27 olish uchun 24 va 3'ni qo'shing.

$$\frac{27}{4}-\frac{7}{8}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{27}{4} va \frac{7}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{54}{8}-\frac{7}{8}$$

\frac{54}{8} va \frac{7}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{54-7}{8}$$

47 olish uchun 54 dan 7 ni ayirish.

$$\frac{47}{8}$$

Omil

$$\frac{47}{2 ^ {3}} = 5\frac{7}{8} = 5,875$$
