Yechim qadamlari

48 hosil qilish uchun 12 va 4 ni ko'paytirish.

$$\frac{48+1}{4}+\frac{1}{6}-\frac{1\times 8+7}{8}$$

49 olish uchun 48 va 1'ni qo'shing.

$$\frac{49}{4}+\frac{1}{6}-\frac{1\times 8+7}{8}$$

4 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{49}{4} va \frac{1}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{147}{12}+\frac{2}{12}-\frac{1\times 8+7}{8}$$

\frac{147}{12} va \frac{2}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{147+2}{12}-\frac{1\times 8+7}{8}$$

149 olish uchun 147 va 2'ni qo'shing.

$$\frac{149}{12}-\frac{1\times 8+7}{8}$$

8 hosil qilish uchun 1 va 8 ni ko'paytirish.

$$\frac{149}{12}-\frac{8+7}{8}$$

15 olish uchun 8 va 7'ni qo'shing.

$$\frac{149}{12}-\frac{15}{8}$$

12 va 8 ning eng kichik umumiy karralisi 24 ga teng. \frac{149}{12} va \frac{15}{8} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{298}{24}-\frac{45}{24}$$

\frac{298}{24} va \frac{45}{24} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{298-45}{24}$$

253 olish uchun 298 dan 45 ni ayirish.

$$\frac{253}{24}$$
