Yechim qadamlari

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{9+1}{3}\times \frac{5\times 5+2}{5}+\frac{25}{625}$$

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

$$\frac{10}{3}\times \frac{5\times 5+2}{5}+\frac{25}{625}$$

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

$$\frac{10}{3}\times \frac{25+2}{5}+\frac{25}{625}$$

27 olish uchun 25 va 2'ni qo'shing.

$$\frac{10}{3}\times \frac{27}{5}+\frac{25}{625}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{10}{3} ni \frac{27}{5} ga ko‘paytiring.

$$\frac{10\times 27}{3\times 5}+\frac{25}{625}$$

\frac{10\times 27}{3\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{270}{15}+\frac{25}{625}$$

18 ni olish uchun 270 ni 15 ga bo‘ling.

$$18+\frac{25}{625}$$

\frac{25}{625} ulushini 25 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$18+\frac{1}{25}$$

18 ni \frac{450}{25} kasrga o‘giring.

$$\frac{450}{25}+\frac{1}{25}$$

\frac{450}{25} va \frac{1}{25} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{450+1}{25}$$

451 olish uchun 450 va 1'ni qo'shing.

$$\frac{451}{25}$$

Omil

$$\frac{11 \cdot 41}{5 ^ {2}} = 18\frac{1}{25} = 18,04$$
