Step-by-step solution for: Decimal Subtraction Worksheets
Let’s solve each subtraction problem step by step. We’ll line up the decimals and subtract carefully, borrowing when needed.
---
1) 6.928 - 2.365
```
6.928
- 2.365
-------
4.563
```
→ 8 - 5 = 3
→ 2 - 6 → borrow: 12 - 6 = 6 (9 becomes 8)
→ 8 - 3 = 5
→ 6 - 2 = 4
✔ 4.563
---
2) 78.07 - 43.55
Write as 78.07 - 43.55
```
78.07
- 43.55
-------
34.52
```
→ 7 - 5 = 2
→ 0 - 5 → borrow: 10 - 5 = 5 (8 becomes 7)
→ 7 - 3 = 4
→ 7 - 4 = 3
✔ 34.52
---
3) 91.24 - 85.76
```
91.24
- 85.76
-------
5.48
```
→ 4 - 6 → borrow: 14 - 6 = 8 (2 becomes 1)
→ 1 - 7 → borrow: 11 - 7 = 4 (1 becomes 0, then 9 becomes 8)
→ 0 - 5 → borrow: 10 - 5 = 5 (9 becomes 8)
→ 8 - 8 = 0 → so we get 5.48
✔ 5.48
---
4) 670.2 - 158.8
Write as 670.20 - 158.80
```
670.20
- 158.80
--------
511.40
```
→ 0 - 0 = 0
→ 2 - 8 → borrow: 12 - 8 = 4 (0 becomes 9, 7 becomes 6)
→ 9 - 8 = 1
→ 6 - 5 = 1
→ 6 - 1 = 5
✔ 511.4
---
5) 5.037 - 2.475
```
5.037
- 2.475
-------
2.562
```
→ 7 - 5 = 2
→ 3 - 7 → borrow: 13 - 7 = 6 (0 becomes 9, 5 becomes 4)
→ 9 - 4 = 5
→ 4 - 2 = 2
✔ 2.562
---
6) 71.25 - 67.89
```
71.25
- 67.89
-------
3.36
```
→ 5 - 9 → borrow: 15 - 9 = 6 (2 becomes 1)
→ 1 - 8 → borrow: 11 - 8 = 3 (1 becomes 0, 7 becomes 6)
→ 0 - 7 → borrow: 10 - 7 = 3 (7 becomes 6)
→ 6 - 6 = 0 → so 3.36
✔ 3.36
---
7) 30.37 - 9.75
```
30.37
- 9.75
-------
20.62
```
→ 7 - 5 = 2
→ 3 - 7 → borrow: 13 - 7 = 6 (0 becomes 9, 3 becomes 2)
→ 9 - 9 = 0
→ 2 - 0 = 2
✔ 20.62
---
8) 67.2 - 38.45
Write as 67.20 - 38.45
```
67.20
- 38.45
-------
28.75
```
→ 0 - 5 → borrow: 10 - 5 = 5 (2 becomes 1)
→ 1 - 4 → borrow: 11 - 4 = 7 (7 becomes 6)
→ 6 - 8 → borrow: 16 - 8 = 8 (6 becomes 5)
→ 5 - 3 = 2
✔ 28.75
---
9) 4.172 - 0.684
```
4.172
- 0.684
-------
3.488
```
→ 2 - 4 → borrow: 12 - 4 = 8 (7 becomes 6)
→ 6 - 8 → borrow: 16 - 8 = 8 (1 becomes 0, 4 becomes 3)
→ 0 - 6 → borrow: 10 - 6 = 4 (3 becomes 2? Wait — let's redo carefully)
Actually:
Start from right:
Thousandths: 2 < 4 → borrow from hundredths → 12 - 4 = 8 → hundredths digit was 7, now 6
Hundredths: 6 < 8 → borrow from tenths → 16 - 8 = 8 → tenths digit was 1, now 0
Tenths: 0 < 6 → borrow from units → 10 - 6 = 4 → units digit was 4, now 3
Units: 3 - 0 = 3
So: 3.488 ✔

→ 5 - 2 = 3
✔ 370.3
---
13) 8.403 - 1.675
```
8.403
- 1.675
-------
6.728
```
→ 3 - 5 → borrow: 13 - 5 = 8 (0 becomes 9, but wait — 0 can’t lend, so go to 4)
Better:
Thousandths: 3 < 5 → borrow from hundredths → but hundredths is 0 → so borrow from tenths → tenths is 4 → becomes 3, hundredths becomes 10 → then lend to thousandths → hundredths becomes 9, thousandths becomes 13
→ 13 - 5 = 8
→ 9 - 7 = 2
→ 3 - 6 → borrow: 13 - 6 = 7 (8 becomes 7)
