Yechim qadamlari

0 hosil qilish uchun 0 va 825 ni ko'paytirish.

$$30+0\times 30+\frac{15}{100}\times 30$$

0 hosil qilish uchun 0 va 30 ni ko'paytirish.

$$30+0+\frac{15}{100}\times 30$$

30 olish uchun 30 va 0'ni qo'shing.

$$30+\frac{15}{100}\times 30$$

\frac{15}{100} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$30+\frac{3}{20}\times 30$$

\frac{3}{20}\times 30 ni yagona kasrga aylantiring.

$$30+\frac{3\times 30}{20}$$

90 hosil qilish uchun 3 va 30 ni ko'paytirish.

$$30+\frac{90}{20}$$

\frac{90}{20} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$30+\frac{9}{2}$$

30 ni \frac{60}{2} kasrga o‘giring.

$$\frac{60}{2}+\frac{9}{2}$$

\frac{60}{2} va \frac{9}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{60+9}{2}$$

69 olish uchun 60 va 9'ni qo'shing.

$$\frac{69}{2}$$

Omil

$$\frac{3 \cdot 23}{2} = 34\frac{1}{2} = 34,5$$
