Fourth Grade Fractions Math Worksheets - Twisty Noodle - Free Printable

Let’s solve each problem step by step. All these problems are about adding or subtracting fractions that have the same denominator (bottom number). When denominators are the same, you just add or subtract the numerators (top numbers) and keep the denominator the same.

---

1. 2/5 - 1/5 = ?
Subtract numerators: 2 - 1 = 1
Keep denominator: 5
→ 1/5

2. 4/9 - 1/9 = ?
4 - 1 = 3
→ 3/9 → This can be simplified to 1/3, but since the worksheet doesn’t ask for simplifying, we’ll leave it as 3/9 unless told otherwise. But let’s check — in school, sometimes they want simplest form. Let’s simplify all answers where possible to be safe.

Wait — looking at the problems, many will simplify. Let’s do that consistently.

So 3/9 = 1/3 → 1/3

But actually, let me double-check the instructions — there’s no instruction to simplify, but in most elementary worksheets, they expect simplified answers. To be accurate, I’ll compute first, then simplify if needed.

Actually, let’s go one by one and simplify only when obvious and standard.

But to avoid confusion, I’ll give both unsimplified and simplified? No — better to follow common practice: simplify final answer.

Let me redo with simplification:

---

1. 2/5 - 1/5 = 1/5 → already simplified → 1/5

2. 4/9 - 1/9 = 3/9 = 1/3 → 1/3

3. 5/7 + 1/7 = 6/7 → already simplified → 6/7

4. 2/4 + 1/4 = 3/4 → already simplified → 3/4

5. 7/10 - 4/10 = 3/10 → already simplified → 3/10

6. 4/6 - 1/6 = 3/6 = 1/2 → 1/2

7. 2/4 + 1/4 = 3/4 → same as #4 → 3/4

8. 2/11 + 1/11 = 3/11 → already simplified → 3/11

9. 1/3 + 1/3 = 2/3 → already simplified → 2/3

10. 2/3 - 1/3 = 1/3 → already simplified → 1/3

11. 3/8 - 1/8 = 2/8 = 1/4 → 1/4

12. 4/12 - 1/12 = 3/12 = 1/4 → 1/4

13. 3/6 + 1/6 = 4/6 = 2/3 → 2/3

14. 3/5 - 2/5 = 1/5 → already simplified → 1/5

---

Now let’s list them in order as they appear on the sheet (left column top to bottom, then right column top to bottom):

Left Column:
1. 2/5 - 1/5 = 1/5
2. 5/7 + 1/7 = 6/7
3. 7/10 - 4/10 = 3/10
4. 2/4 + 1/4 = 3/4
5. 1/3 + 1/3 = 2/3
6. 3/8 - 1/8 = 1/4
7. 3/6 + 1/6 = 2/3

Right Column:
8. 4/9 - 1/9 = 1/3
9. 2/4 + 1/4 = 3/4
10. 4/6 - 1/6 = 1/2
11. 2/11 + 1/11 = 3/11
12. 2/3 - 1/3 = 1/3
13. 4/12 - 1/12 = 1/4
14. 3/5 - 2/5 = 1/5

Wait — let me count again. The image has 7 rows × 2 columns = 14 problems.

Listing by row:

Row 1:
Left: 2/5 - 1/5 = 1/5
Right: 4/9 - 1/9 = 3/9 = 1/3

Row 2:
Left: 5/7 + 1/7 = 6/7
Right: 2/4 + 1/4 = 3/4

Row 3:
Left: 7/10 - 4/10 = 3/10
Right: 4/6 - 1/6 = 3/6 = 1/2

Row 4:
Left: 2/4 + 1/4 = 3/4
Right: 2/11 + 1/11 = 3/11

Row 5:
Left: 1/3 + 1/3 = 2/3
Right: 2/3 - 1/3 = 1/3

Row 6:
Left: 3/8 - 1/8 = 2/8 = 1/4
Right: 4/12 - 1/12 = 3/12 = 1/4

Row 7:
Left: 3/6 + 1/6 = 4/6 = 2/3
Right: 3/5 - 2/5 = 1/5

All correct.

Final Answer:

1/5, 1/3, 6/7, 3/4, 3/10, 1/2, 3/4, 3/11, 2/3, 1/3, 1/4, 1/4, 2/3, 1/5

But since the worksheet has boxes, probably expects each answer in its box. So I’ll list them in order as per the grid.

To match the layout:

First column (top to bottom):
1/5
6/7
3/10
3/4
2/3
1/4
2/3

Second column (top to bottom):
1/3
3/4
1/2
3/11
1/3
1/4
1/5

Yes.

Final Answer:
1/5, 6/7, 3/10, 3/4, 2/3, 1/4, 2/3, 1/3, 3/4, 1/2, 3/11, 1/3, 1/4, 1/5

But to present clearly, perhaps as a list matching the rows.

Since the user didn't specify format, I'll write them in order left to right, top to bottom.

So:

Row 1: 1/5 and 1/3
Row 2: 6/7 and 3/4
Row 3: 3/10 and 1/2
Row 4: 3/4 and 3/11
Row 5: 2/3 and 1/3
Row 6: 1/4 and 1/4
Row 7: 2/3 and 1/5

That’s the complete set.

Final Answer:
1/5, 1/3, 6/7, 3/4, 3/10, 1/2, 3/4, 3/11, 2/3, 1/3, 1/4, 1/4, 2/3, 1/5
