Yechim qadamlari

200 hosil qilish uchun 40 va 5 ni ko'paytirish.

$$\frac{200+2}{5}-\frac{12\times 5+2}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

202 olish uchun 200 va 2'ni qo'shing.

$$\frac{202}{5}-\frac{12\times 5+2}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

60 hosil qilish uchun 12 va 5 ni ko'paytirish.

$$\frac{202}{5}-\frac{60+2}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

62 olish uchun 60 va 2'ni qo'shing.

$$\frac{202}{5}-\frac{62}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

\frac{202}{5} va \frac{62}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{202-62}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

140 olish uchun 202 dan 62 ni ayirish.

$$\frac{140}{5}-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

28 ni olish uchun 140 ni 5 ga bo‘ling.

$$28-\frac{\frac{12\times 5+2}{5}+\frac{1\times 5+3}{5}}{3}$$

60 hosil qilish uchun 12 va 5 ni ko'paytirish.

$$28-\frac{\frac{60+2}{5}+\frac{1\times 5+3}{5}}{3}$$

62 olish uchun 60 va 2'ni qo'shing.

$$28-\frac{\frac{62}{5}+\frac{1\times 5+3}{5}}{3}$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$28-\frac{\frac{62}{5}+\frac{5+3}{5}}{3}$$

8 olish uchun 5 va 3'ni qo'shing.

$$28-\frac{\frac{62}{5}+\frac{8}{5}}{3}$$

\frac{62}{5} va \frac{8}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$28-\frac{\frac{62+8}{5}}{3}$$

70 olish uchun 62 va 8'ni qo'shing.

$$28-\frac{\frac{70}{5}}{3}$$

14 ni olish uchun 70 ni 5 ga bo‘ling.

$$28-\frac{14}{3}$$

28 ni \frac{84}{3} kasrga o‘giring.

$$\frac{84}{3}-\frac{14}{3}$$

\frac{84}{3} va \frac{14}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{84-14}{3}$$

70 olish uchun 84 dan 14 ni ayirish.

$$\frac{70}{3}$$

Omil

$$\frac{2 \cdot 5 \cdot 7}{3} = 23\frac{1}{3} = 23,333333333333332$$
