Yechim qadamlari

30 hosil qilish uchun 15 va 2 ni ko'paytirish.

$$\frac{30+1}{2}+\frac{7\times 3+2}{3}-\frac{9\times 4+1}{4}$$

31 olish uchun 30 va 1'ni qo'shing.

$$\frac{31}{2}+\frac{7\times 3+2}{3}-\frac{9\times 4+1}{4}$$

21 hosil qilish uchun 7 va 3 ni ko'paytirish.

$$\frac{31}{2}+\frac{21+2}{3}-\frac{9\times 4+1}{4}$$

23 olish uchun 21 va 2'ni qo'shing.

$$\frac{31}{2}+\frac{23}{3}-\frac{9\times 4+1}{4}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{31}{2} va \frac{23}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{93}{6}+\frac{46}{6}-\frac{9\times 4+1}{4}$$

\frac{93}{6} va \frac{46}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{93+46}{6}-\frac{9\times 4+1}{4}$$

139 olish uchun 93 va 46'ni qo'shing.

$$\frac{139}{6}-\frac{9\times 4+1}{4}$$

36 hosil qilish uchun 9 va 4 ni ko'paytirish.

$$\frac{139}{6}-\frac{36+1}{4}$$

37 olish uchun 36 va 1'ni qo'shing.

$$\frac{139}{6}-\frac{37}{4}$$

6 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{139}{6} va \frac{37}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{278}{12}-\frac{111}{12}$$

\frac{278}{12} va \frac{111}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{278-111}{12}$$

167 olish uchun 278 dan 111 ni ayirish.

$$\frac{167}{12}$$

Omil

$$\frac{167}{2 ^ {2} \cdot 3} = 13\frac{11}{12} = 13,916666666666666$$
