6-2*13/4 eching

$$6 - 2 \times 1 \frac { 3 } { 4 }$$

Baholash

$$\frac{5}{2}=2,5$$

Yechim qadamlari

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$6-2\times \frac{4+3}{4}$$

7 olish uchun 4 va 3'ni qo'shing.

$$6-2\times \frac{7}{4}$$

2\times \frac{7}{4} ni yagona kasrga aylantiring.

$$6-\frac{2\times 7}{4}$$

14 hosil qilish uchun 2 va 7 ni ko'paytirish.

$$6-\frac{14}{4}$$

\frac{14}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$6-\frac{7}{2}$$

6 ni \frac{12}{2} kasrga o‘giring.

$$\frac{12}{2}-\frac{7}{2}$$

\frac{12}{2} va \frac{7}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{12-7}{2}$$

5 olish uchun 12 dan 7 ni ayirish.

$$\frac{5}{2}$$

Omil

$$\frac{5}{2} = 2\frac{1}{2} = 2,5$$
