Yechim qadamlari

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

$$25-\frac{\frac{4}{9}}{8}+28$$

\frac{\frac{4}{9}}{8} ni yagona kasrga aylantiring.

$$25-\frac{4}{9\times 8}+28$$

72 hosil qilish uchun 9 va 8 ni ko'paytirish.

$$25-\frac{4}{72}+28$$

\frac{4}{72} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$25-\frac{1}{18}+28$$

25 ni \frac{450}{18} kasrga o‘giring.

$$\frac{450}{18}-\frac{1}{18}+28$$

\frac{450}{18} va \frac{1}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{450-1}{18}+28$$

449 olish uchun 450 dan 1 ni ayirish.

$$\frac{449}{18}+28$$

28 ni \frac{504}{18} kasrga o‘giring.

$$\frac{449}{18}+\frac{504}{18}$$

\frac{449}{18} va \frac{504}{18} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{449+504}{18}$$

953 olish uchun 449 va 504'ni qo'shing.

$$\frac{953}{18}$$
