3/5-7/1=3*7-5*7= eching

$$\frac { 3 } { 5 } - \frac { 7 } { 1 } = 3 \times 7 - 5 \times 7 =$$

Yechim qadamlari

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

$$\frac{3}{5}-7=3\times 7-5\times 7$$

7 ni \frac{35}{5} kasrga o‘giring.

$$\frac{3}{5}-\frac{35}{5}=3\times 7-5\times 7$$

\frac{3}{5} va \frac{35}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-35}{5}=3\times 7-5\times 7$$

-32 olish uchun 3 dan 35 ni ayirish.

$$-\frac{32}{5}=3\times 7-5\times 7$$

21 hosil qilish uchun 3 va 7 ni ko'paytirish.

$$-\frac{32}{5}=21-5\times 7$$

35 hosil qilish uchun 5 va 7 ni ko'paytirish.

$$-\frac{32}{5}=21-35$$

-14 olish uchun 21 dan 35 ni ayirish.

$$-\frac{32}{5}=-14$$

-14 ni -\frac{70}{5} kasrga o‘giring.

$$-\frac{32}{5}=-\frac{70}{5}$$

-\frac{32}{5} va -\frac{70}{5} ni taqqoslang.
