Here are the solutions for the addition problems. I have aligned the decimal points to make sure each digit is in the correct place value column before adding.
Row 1:
1. $0.74 + 4.15 = 4.89$
2. $32.58 + 90.92 = 123.50$ (or $123.5$)
3. $99.8 + 67.2 = 167.0$ (or $167$)
Row 2:
4. $835.77 + 977.89 = 1813.66$
5. $680.53 + 100.16 = 780.69$
6. $1.8 + 695.9 = 697.7$
Row 3:
7. $47.757 + 8.009 = 55.766$
8. $62.92 + 64.73 = 127.65$
9. $81.29 + 10.99 = 92.28$
Row 4:
10. $170.001 + 22.167 = 192.168$
11. $96.234 + 134.673 = 230.907$
12. $551.260 + 720.952 = 1272.212$
Row 5:
13. $43.01 + 75.86 = 118.87$
14. $2.127 + 2.981 = 5.108$
15. $0.0015 + 1.0090 = 1.0105$
Final Answer:
1. 4.89
2. 123.5
3. 167
4. 1813.66
5. 780.69
6. 697.7
7. 55.766
8. 127.65
9. 92.28
10. 192.168
11. 230.907
12. 1272.212
13. 118.87
14. 5.108
15. 1.0105
