Yechim qadamlari

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

$$\left(\frac{3}{4}+\frac{16+3}{8}\right)\times 258$$

19 olish uchun 16 va 3'ni qo'shing.

$$\left(\frac{3}{4}+\frac{19}{8}\right)\times 258$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{4} va \frac{19}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{6}{8}+\frac{19}{8}\right)\times 258$$

\frac{6}{8} va \frac{19}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+19}{8}\times 258$$

25 olish uchun 6 va 19'ni qo'shing.

$$\frac{25}{8}\times 258$$

\frac{25}{8}\times 258 ni yagona kasrga aylantiring.

$$\frac{25\times 258}{8}$$

6450 hosil qilish uchun 25 va 258 ni ko'paytirish.

$$\frac{6450}{8}$$

\frac{6450}{8} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3225}{4}$$
