Understand the Problem

The question is asking to solve a series of addition problems involving decimals. Each equation needs to be evaluated to find the sum.

Answer

1. 55.2 2. 46.4 3. 34.3 4. 18.0 5. 35.1 6. 7.03 7. 104.24 8. 40.0 9. 18.15 10. 13.85

Steps to Solve

Identify the equations Each equation needs to be evaluated to find the sum. The equations to be solved are:
- 45.3 + 9.9
- 6.7 + 39.7
- 16.8 + 17.5
- 9.2 + 8.8
- 16.3 + 18.8
- 2.53 + 4.5
- 95.6 + 8.64
- 17.7 + 22.3
- 8.95 + 9.2
- 6.3 + 7.55
Calculate the sums Using straightforward addition for each equation:
- For 1: $$ 45.3 + 9.9 = 55.2 $$
- For 2: $$ 6.7 + 39.7 = 46.4 $$
- For 3: $$ 16.8 + 17.5 = 34.3 $$
- For 4: $$ 9.2 + 8.8 = 18.0 $$
- For 5: $$ 16.3 + 18.8 = 35.1 $$
- For 6: $$ 2.53 + 4.5 = 7.03 $$
- For 7: $$ 95.6 + 8.64 = 104.24 $$
- For 8: $$ 17.7 + 22.3 = 40.0 $$
- For 9: $$ 8.95 + 9.2 = 18.15 $$
- For 10: $$ 6.3 + 7.55 = 13.85 $$
Summarize the results We find the results for each equation as follows:
- 45.3 + 9.9 = 55.2
- 6.7 + 39.7 = 46.4
- 16.8 + 17.5 = 34.3
- 9.2 + 8.8 = 18.0
- 16.3 + 18.8 = 35.1
- 2.53 + 4.5 = 7.03
- 95.6 + 8.64 = 104.24
- 17.7 + 22.3 = 40.0
- 8.95 + 9.2 = 18.15
- 6.3 + 7.55 = 13.85

More Information

Adding decimals is similar to adding whole numbers; align the decimal points and add as usual. The results show the addition of various decimal values.

Tips

Neglecting to align decimal points can lead to incorrect sums.
Failing to carry over when the sum exceeds a single digit in a column.
Misplacing the decimal in the final answer.
