Baholash

$$\frac{102}{25}=4,08$$

Yechim qadamlari

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

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

6 olish uchun 5 va 1'ni qo'shing.

$$\frac{6}{5}\times \frac{3\times 5+2}{5}$$

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

$$\frac{6}{5}\times \frac{15+2}{5}$$

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

$$\frac{6}{5}\times \frac{17}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{6}{5} ni \frac{17}{5} ga ko‘paytiring.

$$\frac{6\times 17}{5\times 5}$$

\frac{6\times 17}{5\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{102}{25}$$

Omil

$$\frac{2 \cdot 3 \cdot 17}{5 ^ {2}} = 4\frac{2}{25} = 4,08$$
