Yechim qadamlari

10 hosil qilish uchun 5 va 2 ni ko'paytirish.

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

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

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

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

$$\frac{11}{2}\times \frac{21+2}{7}$$

23 olish uchun 21 va 2'ni qo'shing.

$$\frac{11}{2}\times \frac{23}{7}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{11}{2} ni \frac{23}{7} ga ko‘paytiring.

$$\frac{11\times 23}{2\times 7}$$

\frac{11\times 23}{2\times 7} kasridagi ko‘paytirishlarni bajaring.

$$\frac{253}{14}$$

Omil

$$\frac{11 \cdot 23}{2 \cdot 7} = 18\frac{1}{14} = 18,071428571428573$$
