81/2+(-1/4)-5-5*025 eching

$$8 \frac { 1 } { 2 } + ( - \frac { 1 } { 4 } ) - 5 - 5 \times 025$$

Baholash

$$\frac{13}{4}=3,25$$

Yechim qadamlari

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

$$\frac{16+1}{2}-\frac{1}{4}-5-5\times 0\times 25$$

17 olish uchun 16 va 1'ni qo'shing.

$$\frac{17}{2}-\frac{1}{4}-5-5\times 0\times 25$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{17}{2} va \frac{1}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{34}{4}-\frac{1}{4}-5-5\times 0\times 25$$

\frac{34}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{34-1}{4}-5-5\times 0\times 25$$

33 olish uchun 34 dan 1 ni ayirish.

$$\frac{33}{4}-5-5\times 0\times 25$$

5 ni \frac{20}{4} kasrga o‘giring.

$$\frac{33}{4}-\frac{20}{4}-5\times 0\times 25$$

\frac{33}{4} va \frac{20}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{33-20}{4}-5\times 0\times 25$$

13 olish uchun 33 dan 20 ni ayirish.

$$\frac{13}{4}-5\times 0\times 25$$

0 hosil qilish uchun 5 va 0 ni ko'paytirish.

$$\frac{13}{4}-0\times 25$$

0 hosil qilish uchun 0 va 25 ni ko'paytirish.

$$\frac{13}{4}-0$$

\frac{13}{4} olish uchun \frac{13}{4} dan 0 ni ayirish.

$$\frac{13}{4}$$

Omil

$$\frac{13}{2 ^ {2}} = 3\frac{1}{4} = 3,25$$
