Yechim qadamlari

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

$$\frac{8+1}{2}\times \frac{1\times 4+3}{4}$$

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

$$\frac{9}{2}\times \frac{1\times 4+3}{4}$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$\frac{9}{2}\times \frac{4+3}{4}$$

7 olish uchun 4 va 3'ni qo'shing.

$$\frac{9}{2}\times \frac{7}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{9}{2} ni \frac{7}{4} ga ko‘paytiring.

$$\frac{9\times 7}{2\times 4}$$

\frac{9\times 7}{2\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{63}{8}$$

Omil

$$\frac{3 ^ {2} \cdot 7}{2 ^ {3}} = 7\frac{7}{8} = 7,875$$
