Yechim qadamlari

14 hosil qilish uchun 7 va 2 ni ko'paytirish.

$$\frac{14+1}{2}-\frac{5\times 3+2}{3}+\frac{6\times 4+1}{4}$$

15 olish uchun 14 va 1'ni qo'shing.

$$\frac{15}{2}-\frac{5\times 3+2}{3}+\frac{6\times 4+1}{4}$$

15 hosil qilish uchun 5 va 3 ni ko'paytirish.

$$\frac{15}{2}-\frac{15+2}{3}+\frac{6\times 4+1}{4}$$

17 olish uchun 15 va 2'ni qo'shing.

$$\frac{15}{2}-\frac{17}{3}+\frac{6\times 4+1}{4}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{15}{2} va \frac{17}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{6}-\frac{34}{6}+\frac{6\times 4+1}{4}$$

\frac{45}{6} va \frac{34}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{45-34}{6}+\frac{6\times 4+1}{4}$$

11 olish uchun 45 dan 34 ni ayirish.

$$\frac{11}{6}+\frac{6\times 4+1}{4}$$

24 hosil qilish uchun 6 va 4 ni ko'paytirish.

$$\frac{11}{6}+\frac{24+1}{4}$$

25 olish uchun 24 va 1'ni qo'shing.

$$\frac{11}{6}+\frac{25}{4}$$

6 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{11}{6} va \frac{25}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{22}{12}+\frac{75}{12}$$

\frac{22}{12} va \frac{75}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{22+75}{12}$$

97 olish uchun 22 va 75'ni qo'shing.

$$\frac{97}{12}$$

Omil

$$\frac{97}{2 ^ {2} \cdot 3} = 8\frac{1}{12} = 8,083333333333334$$
