Answer 1

(4,44 : 3,7 - 0,56 : 2,8) : 0,25 - 0,8 = 3,2

1) 4,44 : 3,7 = 1,2

2) 0,56 : 2,8 = 0,2

3) 1,2 - 0,2 = 1

4) 1 : 0,25 = 4

5) 4 - 0,8 = 3,2

Ответ: 3,2.

Answer 2

Let's break down the expression step by step:

Step 1: Evaluate the division within parentheses. 4.44 : 3.7 = 1.2

Step 2: Evaluate the second division within parentheses. 0.56 : 2.8 = 0.2

Step 3: Subtract the result of the second division from the result of the first division. 1.2 - 0.2 = 1.0

Step 4: Divide the result from Step 3 by 0.25. 1.0 : 0.25 = 4.0

Step 5: Subtract 0.8 from the result of Step 4. 4.0 - 0.8 = 3.2

Therefore, the final result is 3.2.
