81/6-62/5= eching

$$8 \frac { 1 } { 6 } - 6 \frac { 2 } { 5 } =$$

Baholash

$$\frac{53}{30}\approx 1,766666667$$

Yechim qadamlari

48 hosil qilish uchun 8 va 6 ni ko'paytirish.

$$\frac{48+1}{6}-\frac{6\times 5+2}{5}$$

49 olish uchun 48 va 1'ni qo'shing.

$$\frac{49}{6}-\frac{6\times 5+2}{5}$$

30 hosil qilish uchun 6 va 5 ni ko'paytirish.

$$\frac{49}{6}-\frac{30+2}{5}$$

32 olish uchun 30 va 2'ni qo'shing.

$$\frac{49}{6}-\frac{32}{5}$$

6 va 5 ning eng kichik umumiy karralisi 30 ga teng. \frac{49}{6} va \frac{32}{5} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{245}{30}-\frac{192}{30}$$

\frac{245}{30} va \frac{192}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{245-192}{30}$$

53 olish uchun 245 dan 192 ni ayirish.

$$\frac{53}{30}$$

Omil

$$\frac{53}{2 \cdot 3 \cdot 5} = 1\frac{23}{30} = 1,7666666666666666$$
