Answer 1

12,75*4/25=12.75*0.16=2.04
2.04*1.8=3.672
1 1/2*2,04=1.5*2.04=3.06
3.06:20=0.153
3.672:0.153=24

Answer 2

Привожу пример решения, в котором для рационализации вычислений несколько действий выполняются одновременно. Иногда затраченное на решение времени очень ценно.

Answer 3

Calculation

To solve the given expression: (12.75 * 4 / 25 * 1.8) / (1 + 1 / 2 * 2.04:20), we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

1. First, we calculate the value inside the parentheses: - 12.75 * 4 / 25 * 1.8 = 0.51 * 1.8 = 0.918

2. Then, we calculate the value outside the parentheses: - 1 + 1 / 2 * 2.04:20 = 1 + 0.102 = 1.102

3. Finally, we divide the value obtained in step 1 by the value obtained in step 2: - 0.918 / 1.102 ≈ 0.832

Therefore, the result of the given expression is approximately 0.832.

Solution

The given expression: (12.75 * 4 / 25 * 1.8) / (1 + 1 / 2 * 2.04:20) evaluates to approximately 0.832 after following the order of operations.
