Baholash

$$\frac{1}{4}=0,25$$

Yechim qadamlari

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

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

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{3}{2}-\frac{9}{4}+1$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{3}{2} va \frac{9}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{4}-\frac{9}{4}+1$$

\frac{6}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-9}{4}+1$$

-3 olish uchun 6 dan 9 ni ayirish.

$$-\frac{3}{4}+1$$

1 ni \frac{4}{4} kasrga o‘giring.

$$-\frac{3}{4}+\frac{4}{4}$$

-\frac{3}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3+4}{4}$$

1 olish uchun -3 va 4'ni qo'shing.

$$\frac{1}{4}$$

Omil

$$\frac{1}{2 ^ {2}} = 0,25$$
