96.75 - 15.9

Answer 1

I'll solve each problem and give the answer with the correct number of decimal places. I assumed "21.6,038" = 21.6038 and "23.4,784" = 23.4784.

1) 88.38 + 64.9
- Least decimal places = 1 → round to 1 decimal.
- Sum = 153.28 → 153.3

2) 39.28 + 21.6038
- Least decimal places = 2 → round to 2 decimals.
- Sum = 60.8838 → 60.88

3) 62.53 + 21.967
- Least decimal places = 2 → round to 2 decimals.
- Sum = 84.497 → 84.50

4) 18.98 - 23.4784
- Least decimal places = 2 → round to 2 decimals.
- Difference = -4.4984 → -4.50

5) 85.87 - 91.369
- Least decimal places = 2 → round to 2 decimals.
- Difference = -5.499 → -5.50

6) 96.75 - 15.9
- Least decimal places = 1 → round to 1 decimal.
- Difference = 80.85 → 80.9

If you meant the commaed numbers differently, tell me and I will recalculate.
