Answer 2

Ответ:

31,7 - 56 = -24,7

4,17 + 32 = 36,17

90 - 65 : 5 = 77

84 : 7 + 27 = 39

78 - 36 - 42 ÷ 6 = 35

21 + 49 : 7 - 6 = 22

Answer 3

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

1. 31.3 - 564.17 + 3290 - 65 ÷ 584 ÷ 7 + 2778 - 36 - 42 ÷ 621 + 49 ÷ 7 - 6

2. Perform the division operations:

   • 65 ÷ 584 ÷ 7 ≈ 0.0199
   • 42 ÷ 621 ≈ 0.0676
   • 49 ÷ 7 = 7

The expression now looks like this:

31.3 - 564.17 + 3290 - 0.0199 + 2778 - 36 - 0.0676 + 7 - 6

3. Add and subtract from left to right:

   • 31.3 - 564.17 ≈ -532.87
   • -532.87 + 3290 ≈ 2757.13
   • 2757.13 - 0.0199 ≈ 2757.11
   • 2757.11 + 2778 ≈ 20.89
   • 20.89 - 36 ≈ -15.11
   • -15.11 - 0.0676 ≈ -15.18
   • -15.18 + 7 ≈ -8.18
   • -8.18 - 6 ≈ -14.18

So, the result of the given expression is approximately -14.18.
