103/4-81/2 eching

$$10 \frac { 3 } { 4 } - 8 \frac { 1 } { 2 }$$

Baholash

$$\frac{9}{4}=2,25$$

Yechim qadamlari

40 hosil qilish uchun 10 va 4 ni ko'paytirish.

$$\frac{40+3}{4}-\frac{8\times 2+1}{2}$$

43 olish uchun 40 va 3'ni qo'shing.

$$\frac{43}{4}-\frac{8\times 2+1}{2}$$

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

$$\frac{43}{4}-\frac{16+1}{2}$$

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

$$\frac{43}{4}-\frac{17}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{43}{4} va \frac{17}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{43}{4}-\frac{34}{4}$$

\frac{43}{4} va \frac{34}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{43-34}{4}$$

9 olish uchun 43 dan 34 ni ayirish.

$$\frac{9}{4}$$

Omil

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