Here are the solutions to the addition problems. I have calculated each one carefully by lining up the decimal points.
Left Column:
1. $45.3 + 9.9 = 55.2$
2. $6.7 + 39.7 = 46.4$
3. $16.8 + 17.5 = 34.3$
4. $9.2 + 8.8 = 18.0$ (or just 18)
5. $16.3 + 18.8 = 35.1$
6. $2.53 + 4.5 = 7.03$
7. $95.6 + 8.64 = 104.24$
8. $17.7 + 22.3 = 40.0$ (or just 40)
9. $8.95 + 9.2 = 18.15$
10. $6.3 + 7.55 = 13.85$
Right Column:
1. $9.63 + 2.88 = 12.51$
2. $5.74 + 9.9 = 15.64$
3. $4.12 + 6.31 = 10.43$
4. $92.3 + 9.32 = 101.62$
5. $74.3 + 83.5 = 157.8$
6. $4.21 + 9.6 = 13.81$
7. $47.3 + 52.9 = 100.2$
8. $45.4 + 8.6 = 54.0$ (or just 54)
9. $36.2 + 4.78 = 40.98$
10. $6.63 + 82.1 = 88.73$
Final Answer:
