$$\frac{11}{4}=2,75$$

Yechim qadamlari

24 hosil qilish uchun 3 va 8 ni ko'paytirish.

$$\frac{24+1}{8}-\frac{3}{2}\times \frac{1}{4}$$

25 olish uchun 24 va 1'ni qo'shing.

$$\frac{25}{8}-\frac{3}{2}\times \frac{1}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{2} ni \frac{1}{4} ga ko‘paytiring.

$$\frac{25}{8}-\frac{3\times 1}{2\times 4}$$

\frac{3\times 1}{2\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{25}{8}-\frac{3}{8}$$

\frac{25}{8} va \frac{3}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{25-3}{8}$$

22 olish uchun 25 dan 3 ni ayirish.

$$\frac{22}{8}$$

\frac{22}{8} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{11}{4}$$

Omil

$$\frac{11}{2 ^ {2}} = 2\frac{3}{4} = 2,75$$
