Yechim qadamlari

3 ni olish uchun 12 ni 4 ga bo‘ling.

$$3+\frac{5}{8}-\frac{7}{12}$$

3 ni \frac{24}{8} kasrga o‘giring.

$$\frac{24}{8}+\frac{5}{8}-\frac{7}{12}$$

\frac{24}{8} va \frac{5}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{24+5}{8}-\frac{7}{12}$$

29 olish uchun 24 va 5'ni qo'shing.

$$\frac{29}{8}-\frac{7}{12}$$

8 va 12 ning eng kichik umumiy karralisi 24 ga teng. \frac{29}{8} va \frac{7}{12} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{87}{24}-\frac{14}{24}$$

\frac{87}{24} va \frac{14}{24} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{87-14}{24}$$

73 olish uchun 87 dan 14 ni ayirish.

$$\frac{73}{24}$$

Omil

$$\frac{73}{2 ^ {3} \cdot 3} = 3\frac{1}{24} = 3,0416666666666665$$
