61/2-31/8 eching

$$6 \frac { 1 } { 2 } - 3 \frac { 1 } { 8 }$$

Baholash

$$\frac{27}{8}=3,375$$

Yechim qadamlari

12 hosil qilish uchun 6 va 2 ni ko'paytirish.

$$\frac{12+1}{2}-\frac{3\times 8+1}{8}$$

13 olish uchun 12 va 1'ni qo'shing.

$$\frac{13}{2}-\frac{3\times 8+1}{8}$$

24 hosil qilish uchun 3 va 8 ni ko'paytirish.

$$\frac{13}{2}-\frac{24+1}{8}$$

25 olish uchun 24 va 1'ni qo'shing.

$$\frac{13}{2}-\frac{25}{8}$$

2 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{13}{2} va \frac{25}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{52}{8}-\frac{25}{8}$$

\frac{52}{8} va \frac{25}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{52-25}{8}$$

27 olish uchun 52 dan 25 ni ayirish.

$$\frac{27}{8}$$

Omil

$$\frac{3 ^ {3}}{2 ^ {3}} = 3\frac{3}{8} = 3,375$$
