53 olish uchun 35 va 18'ni qo'shing.

$$60+2\times \frac{53}{5}-\left(7\times 3-18-2+13\right)$$

2\times \frac{53}{5} ni yagona kasrga aylantiring.

$$60+\frac{2\times 53}{5}-\left(7\times 3-18-2+13\right)$$

106 hosil qilish uchun 2 va 53 ni ko'paytirish.

$$60+\frac{106}{5}-\left(7\times 3-18-2+13\right)$$

60 ni \frac{300}{5} kasrga o‘giring.

$$\frac{300}{5}+\frac{106}{5}-\left(7\times 3-18-2+13\right)$$

\frac{300}{5} va \frac{106}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{300+106}{5}-\left(7\times 3-18-2+13\right)$$

406 olish uchun 300 va 106'ni qo'shing.

$$\frac{406}{5}-\left(7\times 3-18-2+13\right)$$

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

$$\frac{406}{5}-\left(21-18-2+13\right)$$

3 olish uchun 21 dan 18 ni ayirish.

$$\frac{406}{5}-\left(3-2+13\right)$$

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{406}{5}-\left(1+13\right)$$

14 olish uchun 1 va 13'ni qo'shing.

$$\frac{406}{5}-14$$

14 ni \frac{70}{5} kasrga o‘giring.

$$\frac{406}{5}-\frac{70}{5}$$

\frac{406}{5} va \frac{70}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{406-70}{5}$$

336 olish uchun 406 dan 70 ni ayirish.

$$\frac{336}{5}$$

Omil

$$\frac{2 ^ {4} \cdot 3 \cdot 7}{5} = 67\frac{1}{5} = 67,2$$
