Yechim qadamlari

4 ni olish uchun 20 ni 5 ga bo‘ling.

$$1+4\times \frac{7}{3}\times 7-2\times \frac{12}{2}$$

4\times \frac{7}{3} ni yagona kasrga aylantiring.

$$1+\frac{4\times 7}{3}\times 7-2\times \frac{12}{2}$$

28 hosil qilish uchun 4 va 7 ni ko'paytirish.

$$1+\frac{28}{3}\times 7-2\times \frac{12}{2}$$

\frac{28}{3}\times 7 ni yagona kasrga aylantiring.

$$1+\frac{28\times 7}{3}-2\times \frac{12}{2}$$

196 hosil qilish uchun 28 va 7 ni ko'paytirish.

$$1+\frac{196}{3}-2\times \frac{12}{2}$$

1 ni \frac{3}{3} kasrga o‘giring.

$$\frac{3}{3}+\frac{196}{3}-2\times \frac{12}{2}$$

\frac{3}{3} va \frac{196}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+196}{3}-2\times \frac{12}{2}$$

199 olish uchun 3 va 196'ni qo'shing.

$$\frac{199}{3}-2\times \frac{12}{2}$$

6 ni olish uchun 12 ni 2 ga bo‘ling.

$$\frac{199}{3}-2\times 6$$

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

$$\frac{199}{3}-12$$

12 ni \frac{36}{3} kasrga o‘giring.

$$\frac{199}{3}-\frac{36}{3}$$

\frac{199}{3} va \frac{36}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{199-36}{3}$$

163 olish uchun 199 dan 36 ni ayirish.

$$\frac{163}{3}$$

Omil

$$\frac{163}{3} = 54\frac{1}{3} = 54,333333333333336$$
