Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Evaluate (36-12:0,8) Since division takes precedence over subtraction, we need to calculate 12 divided by 0.8 first: 12 / 0.8 = 15

Now we subtract 15 from 36: 36 - 15 = 21

Step 2: Multiply the result from Step 1 by 2.5 and add 12.5 21 × 2.5 + 12.5 = 52.5 + 12.5 = 65

Step 3: Evaluate the expression 2.5 × (15.23 + 9.57) Add the values inside the parentheses first: 15.23 + 9.57 = 24.8

Now, multiply this sum by 2.5: 2.5 × 24.8 = 62

Step 4: Add the results from Step 2 and Step 3: 65 + 62 = 127

Therefore, the final result is 127.
