11/5-2/7 eching

$$1 \frac { 1 } { 5 } - \frac { 2 } { 7 }$$

Baholash

$$\frac{32}{35}\approx 0,914285714$$

Yechim qadamlari

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{5+1}{5}-\frac{2}{7}$$

6 olish uchun 5 va 1'ni qo'shing.

$$\frac{6}{5}-\frac{2}{7}$$

5 va 7 ning eng kichik umumiy karralisi 35 ga teng. \frac{6}{5} va \frac{2}{7} ni 35 maxraj bilan kasrlarga aylantirib oling.

$$\frac{42}{35}-\frac{10}{35}$$

\frac{42}{35} va \frac{10}{35} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{42-10}{35}$$

32 olish uchun 42 dan 10 ni ayirish.

$$\frac{32}{35}$$

Omil

$$\frac{2 ^ {5}}{5 \cdot 7} = 0,9142857142857143$$
