Baholash

$$\frac{23}{4}=5,75$$

Yechim qadamlari

120 ni \frac{240}{2} kasrga o‘giring.

$$\frac{240}{2}+\frac{1}{2}-\frac{459}{4}$$

\frac{240}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{240+1}{2}-\frac{459}{4}$$

241 olish uchun 240 va 1'ni qo'shing.

$$\frac{241}{2}-\frac{459}{4}$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{241}{2} va \frac{459}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{482}{4}-\frac{459}{4}$$

\frac{482}{4} va \frac{459}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{482-459}{4}$$

23 olish uchun 482 dan 459 ni ayirish.

$$\frac{23}{4}$$

Omil

$$\frac{23}{2 ^ {2}} = 5\frac{3}{4} = 5,75$$
