Yechim qadamlari

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{7}{10} ni \frac{11}{7} ga ko‘paytiring.

$$\frac{7\times 11}{10\times 7}\times \frac{3\times 3+1}{3}\times 2$$

Surat va maxrajdagi ikkala 7 ni qisqartiring.

$$\frac{11}{10}\times \frac{3\times 3+1}{3}\times 2$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{11}{10}\times \frac{9+1}{3}\times 2$$

10 olish uchun 9 va 1'ni qo'shing.

$$\frac{11}{10}\times \frac{10}{3}\times 2$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{11}{10} ni \frac{10}{3} ga ko‘paytiring.

$$\frac{11\times 10}{10\times 3}\times 2$$

Surat va maxrajdagi ikkala 10 ni qisqartiring.

$$\frac{11}{3}\times 2$$

\frac{11}{3}\times 2 ni yagona kasrga aylantiring.

$$\frac{11\times 2}{3}$$

22 hosil qilish uchun 11 va 2 ni ko'paytirish.

$$\frac{22}{3}$$

Omil

$$\frac{2 \cdot 11}{3} = 7\frac{1}{3} = 7,333333333333333$$
