-1(1/2)+9(3)= eching

$$- 1 ( 1 / 2 ) + 9 ( 3 ) =$$

Baholash

$$\frac{53}{2}=26,5$$

Yechim qadamlari

-\frac{1}{2} hosil qilish uchun -1 va \frac{1}{2} ni ko'paytirish.

$$-\frac{1}{2}+9\times 3$$

27 hosil qilish uchun 9 va 3 ni ko'paytirish.

$$-\frac{1}{2}+27$$

27 ni \frac{54}{2} kasrga o‘giring.

$$-\frac{1}{2}+\frac{54}{2}$$

-\frac{1}{2} va \frac{54}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1+54}{2}$$

53 olish uchun -1 va 54'ni qo'shing.

$$\frac{53}{2}$$

Omil

$$\frac{53}{2} = 26\frac{1}{2} = 26,5$$
