Sure! Let’s solve each problem step by step. The task is to
find the sum of decimals — meaning we add the numbers together, carefully aligning decimal points (even if some are whole numbers).
We’ll go one by one:
---
1. 94 + 0.086 + 29
→ Add whole numbers first: 94 + 29 = 123
→ Then add decimal: 123 + 0.086 =
123.086
✔ Answer: 123.086
---
2. 73 + 0.21 + 34
→ 73 + 34 = 107
→ 107 + 0.21 =
107.21
✔ Answer: 107.21
---
3. 82 + 54 + 0.60
→ 82 + 54 = 136
→ 136 + 0.60 =
136.60 (or just 136.6)
✔ Answer: 136.6
---
4. 0.61 + 0.57 + 0.27
→ Add tenths and hundredths:
0.61
+0.57
= 1.18
+0.27
=
1.45
✔ Answer: 1.45
---
5. 0.095 + 0.20 + 45
→ First, 0.095 + 0.20 = 0.295
→ Then 0.295 + 45 =
45.295
✔ Answer: 45.295
---
6. 67 + 0.057 + 23
→ 67 + 23 = 90
→ 90 + 0.057 =
90.057
✔ Answer: 90.057
---
7. 0.31 + 66 + 0.43
→ 0.31 + 0.43 = 0.74
→ 0.74 + 66 =
66.74
✔ Answer: 66.74
---
8. 0.074 + 0.012 + 0.033
→ Add thousandths:
0.074
+0.012
= 0.086
+0.033
=
0.119
✔ Answer: 0.119
---
9. 0.34 + 0.74 + 0.40
→ 0.34 + 0.74 = 1.08
→ 1.08 + 0.40 =
1.48
✔ Answer: 1.48
---
10. 0.91 + 29 + 82
→ 29 + 82 = 111
→ 111 + 0.91 =
111.91
✔ Answer: 111.91
---
11. 72 + 0.78 + 0.097
→ 0.78 + 0.097 = 0.877
→ 72 + 0.877 =
72.877
✔ Answer: 72.877
---
12. 55 + 0.58 + 0.11
→ 0.58 + 0.11 = 0.69
→ 55 + 0.69 =
55.69
✔ Answer: 55.69
---

💡 Tip for Adding Decimals:
Always line up the decimal points vertically when adding manually — or mentally think in terms of place value (tenths, hundredths, etc.). Whole numbers can be thought of as having a decimal point at the end (e.g., 94 = 94.000).
Let me know if you’d like to see any of these worked out vertically! 😊
Parent Tip: Review the logic above to help your child master the concept of addition of decimals worksheet.
