Baholash

$$\frac{153}{10}=15,3$$

Yechim qadamlari

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

$$\frac{8+1}{2}\times \frac{3\times 5+2}{5}$$

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

$$\frac{9}{2}\times \frac{3\times 5+2}{5}$$

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$\frac{9}{2}\times \frac{15+2}{5}$$

17 olish uchun 15 va 2'ni qo'shing.

$$\frac{9}{2}\times \frac{17}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{9}{2} ni \frac{17}{5} ga ko‘paytiring.

$$\frac{9\times 17}{2\times 5}$$

\frac{9\times 17}{2\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{153}{10}$$

Omil

$$\frac{3 ^ {2} \cdot 17}{2 \cdot 5} = 15\frac{3}{10} = 15,3$$
