Yechim qadamlari

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{6+1}{3}+\frac{4\times 9+5}{9}-\frac{1\times 6+1}{6}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{7}{3}+\frac{4\times 9+5}{9}-\frac{1\times 6+1}{6}$$

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

$$\frac{7}{3}+\frac{36+5}{9}-\frac{1\times 6+1}{6}$$

41 olish uchun 36 va 5'ni qo'shing.

$$\frac{7}{3}+\frac{41}{9}-\frac{1\times 6+1}{6}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{7}{3} va \frac{41}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{21}{9}+\frac{41}{9}-\frac{1\times 6+1}{6}$$

\frac{21}{9} va \frac{41}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{21+41}{9}-\frac{1\times 6+1}{6}$$

62 olish uchun 21 va 41'ni qo'shing.

$$\frac{62}{9}-\frac{1\times 6+1}{6}$$

6 hosil qilish uchun 1 va 6 ni ko'paytirish.

$$\frac{62}{9}-\frac{6+1}{6}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{62}{9}-\frac{7}{6}$$

9 va 6 ning eng kichik umumiy karralisi 18 ga teng. \frac{62}{9} va \frac{7}{6} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{124}{18}-\frac{21}{18}$$

\frac{124}{18} va \frac{21}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{124-21}{18}$$

103 olish uchun 124 dan 21 ni ayirish.

$$\frac{103}{18}$$

Omil

$$\frac{103}{2 \cdot 3 ^ {2}} = 5\frac{13}{18} = 5,722222222222222$$
