Tasdiqlamoq

Yechim qadamlari

Tenglamaning ikkala tarafini 10 ga ko'paytirish.

$$3\times \frac{2\times 10+7}{10}=8\times 10+1$$

20 hosil qilish uchun 2 va 10 ni ko'paytirish.

$$3\times \frac{20+7}{10}=8\times 10+1$$

27 olish uchun 20 va 7'ni qo'shing.

$$3\times \frac{27}{10}=8\times 10+1$$

3\times \frac{27}{10} ni yagona kasrga aylantiring.

$$\frac{3\times 27}{10}=8\times 10+1$$

81 hosil qilish uchun 3 va 27 ni ko'paytirish.

$$\frac{81}{10}=8\times 10+1$$

80 hosil qilish uchun 8 va 10 ni ko'paytirish.

$$\frac{81}{10}=80+1$$

81 olish uchun 80 va 1'ni qo'shing.

$$\frac{81}{10}=81$$

81 ni \frac{810}{10} kasrga o‘giring.

$$\frac{81}{10}=\frac{810}{10}$$

\frac{81}{10} va \frac{810}{10} ni taqqoslang.
