Column Subtraction Decimals Sheet 2 - a math worksheet featuring 21 subtraction problems with decimal numbers.

Explanation:
Let's solve each subtraction problem step by step. Remember, when subtracting decimals, you must line up the decimal points and subtract digit by digit, just like with whole numbers.

Problem 1:
92.27
– 29.35
________

Start from the right:
7 – 5 = 2
2 – 3: We can't do this, so borrow 1 from the 2 (which becomes 1), making the 2 into 12.
12 – 3 = 9
Now, 1 (after borrowing) – 9: Again, we can't do this, so borrow from the 9.
The 9 becomes 8, and the 1 becomes 11.
11 – 9 = 2
8 – 2 = 6

So, 92.27 – 29.35 = 62.92

Problem 2:
50.45
– 52.19
________

We are subtracting a larger number from a smaller one, so the result will be negative.
We can do 52.19 – 50.45 and then make it negative.

52.19
–50.45
________

9 – 5 = 4
1 – 4: can't do, borrow → 11 – 4 = 7
1 (after borrowing) – 0 = 1
2 – 0 = 2
5 – 5 = 0

So, 52.19 – 50.45 = 1.74 → Answer is –1.74

---

Problem 3:
17.67
– 8.28
________

7 – 8: can't do, borrow → 17 – 8 = 9
6 (now 5) – 2 = 3
1 – 0 = 1

So, 17.67 – 8.28 = 9.39

---

Problem 4:
738.5
– 375.7
________

5 – 7: can't do, borrow → 15 – 7 = 8
8 (now 7) – 5 = 2
3 – 7: can't do, borrow → 13 – 7 = 6
7 (now 6) – 3 = 3
7 – 0 = 7

So, 738.5 – 375.7 = 362.8

---

Problem 5:
603.8
– 24.38
________

We need to line up decimals. Write 603.8 as 603.80.

603.80
– 24.38
________

0 – 8: borrow → 10 – 8 = 2
7 (now 7) – 3 = 4
3 – 4: borrow → 13 – 4 = 9
0 (now 9) – 2 = 7
6 – 0 = 6

So, 603.8 – 24.38 = 579.42

---

Problem 6:
56.70
– 24.38
________

0 – 8: borrow → 10 – 8 = 2
6 (now 6) – 3 = 3
7 – 4 = 3
5 – 2 = 3

So, 56.70 – 24.38 = 32.32

---

Problem 7:
83.14
– 57.62
________

4 – 2 = 2
1 – 6: borrow → 11 – 6 = 5
2 (now 2) – 7: can't do → borrow → 12 – 7 = 5
7 (now 7) – 5 = 2

So, 83.14 – 57.62 = 25.52

---

Problem 8:
73.75
– 48.38
________

5 – 8: borrow → 15 – 8 = 7
7 (now 6) – 3 = 3
3 – 8: borrow → 13 – 8 = 5
6 (now 6) – 4 = 2

So, 73.75 – 48.38 = 25.37

---

Problem 9:
70.82
– 56.76
________

2 – 6: borrow → 12 – 6 = 6
7 (now 7) – 7 = 0
0 – 6: borrow → 10 – 6 = 4
6 (now 6) – 5 = 1

So, 70.82 – 56.76 = 14.06

---

Problem 10:
632.4
– 62.8
________

Write 62.8 as 62.80

632.40
– 62.80
________

0 – 0 = 0
4 – 8: borrow → 14 – 8 = 6
1 (now 1) – 2: borrow → 11 – 2 = 9
2 (now 2) – 6: borrow → 12 – 6 = 6
5 (now 5) – 0 = 5
6 – 0 = 6

So, 632.4 – 62.8 = 569.6

---

Problem 11:
15.71
– 24.9
________

24.9 is bigger than 15.71, so result is negative.
Do 24.9 – 15.71

24.90
–15.71
________

0 – 1: borrow → 10 – 1 = 9
8 (now 8) – 7 = 1
9 – 5 = 4
4 – 1 = 3
2 – 0 = 2

So, 24.9 – 15.71 = 9.19 → Answer is –9.19

---

Problem 12:
73.40
– 33.75
________

0 – 5: borrow → 10 – 5 = 5
3 (now 3) – 7: borrow → 13 – 7 = 6
3 (now 2) – 3 = 9
7 – 3 = 4

So, 73.40 – 33.75 = 39.65

---

Problem 13:
601.2
– 265.8
________

Write 601.2 as 601.20

601.20
–265.80
________

0 – 0 = 0
2 – 8: borrow → 12 – 8 = 4
1 (now 0) – 8: borrow → 10 – 8 = 2
0 (now 9) – 5 = 4
9 (now 9) – 6 = 3
5 – 2 = 3

So, 601.2 – 265.8 = 335.4

---

0 – 6: borrow → 10 – 6 = 4
3 (now 3) – 5: borrow → 13 – 5 = 8
4 (now 4) – 7: borrow → 14 – 7 = 7
6 (now 6) – 1 = 5

So, 75.4 – 17.56 = 57.84

---

Problem 15:
63.59
– 27.3
________

Write 27.3 as 27.30

63.59
–27.30
________

9 – 0 = 9
5 – 3 = 2
3 – 7: borrow → 13 – 7 = 6
5 (now 5) – 2 = 3

So, 63.59 – 27.3 = 36.29

---

Problem 16:
2.473
– 2.445
________

3 – 5: borrow → 13 – 5 = 8
6 (now 6) – 4 = 2

2 – 2 = 0

So, 2.473 – 2.445 = 0.028

---

Problem 17:
5.829
– 2.377
________

9 – 7 = 2
2 – 7: borrow → 12 – 7 = 5
7 (now 7) – 3 = 4
5 – 2 = 3

So, 5.829 – 2.377 = 3.452

---

Problem 18:
75.54
– 4.284
________

Write 75.54 as 75.540

75.540
– 4.284
________

0 – 4: borrow → 10 – 4 = 6
3 (now 3) – 8: borrow → 13 – 8 = 5
4 (now 4) – 2 = 2
5 – 4 = 1
7 – 0 = 7

So, 75.54 – 4.284 = 71.256

---

Problem 19:
9.738
– 4.284
________

8 – 4 = 4
3 – 8: borrow → 13 – 8 = 5

9 – 4 = 5

So, 9.738 – 4.284 = 5.454

---

Problem 20:
50.02
– 19.98
________

2 – 8: borrow → 12 – 8 = 4
0 (now 9) – 9: borrow → 19 – 9 = 10? Wait — 9 – 9 = 0, but we borrowed so it's 9 (after borrowing) – 9 = 0
Wait — let's do it carefully.

50.02
–19.98
________

2 – 8: borrow → 12 – 8 = 4
0 (now 9) – 9: 9 – 9 = 0
0 (now 9) – 9: 9 – 9 = 0
4 (now 4) – 1 = 3

Wait — 50.02 – 19.98:

Start from right:
2 – 8: borrow → 12 – 8 = 4
0 (now 9) – 9 = 0
0 (now 9) – 9 = 0
4 (now 4) – 1 = 3

So, 50.02 – 19.98 = 30.04

Wait — 50.02 – 19.98 = 30.04? Let’s check:
30.04 + 19.98 = 50.02?
30.04 + 19.98 = 50.02 → Yes, correct.

0 (now 0) – 6: borrow → 10 – 6 = 4
8 (now 8) – 1 = 7
9 – 0 = 9

So, 91.05 – 16.82 = 74.23

---

Problem 23:

– 1.954
________

9 – 4 = 5
0 – 5: borrow → 10 – 5 = 5
2 (now 2) – 9: borrow → 12 – 9 = 3
5 (now 5) – 1 = 4
6 – 0 = 6

So, 6.309 – 1.954 = 4.355
