$$( \frac { 3 } { 4 } - \frac { 1 } { 2 } ) \cdot 3$$

Baholash

$$\frac{3}{4}=0,75$$

Yechim qadamlari

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{3}{4} va \frac{1}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{3}{4}-\frac{2}{4}\right)\times 3$$

\frac{3}{4} va \frac{2}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{1}{4}\times 3$$

\frac{3}{4} hosil qilish uchun \frac{1}{4} va 3 ni ko'paytirish.

$$\frac{3}{4}$$

Omil

$$\frac{3}{2 ^ {2}} = 0,75$$
