Yechim qadamlari

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

$$\frac{50+3}{5}\times \frac{4\times 2+1}{2}$$

53 olish uchun 50 va 3'ni qo'shing.

$$\frac{53}{5}\times \frac{4\times 2+1}{2}$$

8 hosil qilish uchun 4 va 2 ni ko'paytirish.

$$\frac{53}{5}\times \frac{8+1}{2}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{53}{5}\times \frac{9}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{53}{5} ni \frac{9}{2} ga ko‘paytiring.

$$\frac{53\times 9}{5\times 2}$$

\frac{53\times 9}{5\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{477}{10}$$

Omil

$$\frac{3 ^ {2} \cdot 53}{2 \cdot 5} = 47\frac{7}{10} = 47,7$$
