Answer 1

Ответ:

(2,5-75\5)*0,5\(2-1,8):0,4

1)75/5=15

2)2.5-15=-12.5

3)2-1.8=0.2

4)-12.5*0.5=-6.25

5)0.2/0.4=0.5

6)-6.25/0.5=-12.5

Answer 2

Let's break down the expression step by step:

1. Evaluate the parentheses: (2,5 - 75\5) First, let's address the comma in the number 2,5. It appears to be a decimal separator, so we'll treat it as such.

   2.5 - 75/5 = 2.5 - 15 = -12.5

2. Next, we'll perform the division: 0,5(2-1,8) Again, let's treat the commas as decimal separators.

   2 - 1.8 = 0.2 0.5 / 0.2 = 2.5

3. Finally, let's handle the rest of the expression: 2.5 : 0.4

   2.5 / 0.4 = 6.25

So, the overall result of the expression is:

(2,5 - 75\5) * 0,5(2-1,8) : 0,4 = -12.5 * 2.5 : 0.4 = -31.25 : 0.4 = -78.125
