Fraction addition and subtraction worksheet for students to practice problems with like denominators.

Since both ExplainAnswer and TeachTopic are false, I will proceed directly to solving the problems and providing the final answers.

Let me work through each problem carefully:

Section A:
1) 1/4 + 1/4 = 2/4 ✓ (already solved)
2) 2/4 + 1/4 = 3/4
3) 1/4 + 2/4 = 3/4
4) 2/4 + 2/4 = 4/4
5) 3/4 - 1/4 = 2/4
6) 4/4 - 2/4 = 2/4
7) 3/4 - 2/4 = 1/4
8) 3/4 - 3/4 = 0/4

Section B:
1) 1/5 + 2/5 = 3/5
2) 6/8 - 2/8 = 4/8
3) 3/11 + 7/11 = 10/11
4) 5/6 - 1/6 = 4/6
5) 7/9 + 2/9 = 9/9
6) 9/10 - 4/10 = 5/10
7) 8/9 - 7/9 = 1/9
8) 6/10 + 3/10 = 9/10
9) 4/11 - 2/11 = 2/11
10) 1/12 + 7/12 + 3/12 = 11/12
11) 8/11 - 3/11 + 5/11 = 10/11
12) 10/12 - 4/12 - 5/12 = 1/12

Final Answer:
Section A:
1) 2/4
2) 3/4
3) 3/4
4) 4/4
5) 2/4
6) 2/4
7) 1/4
8) 0/4

Section B:
1) 3/5
2) 4/8
3) 10/11
4) 4/6
5) 9/9
6) 5/10
7) 1/9
8) 9/10
9) 2/11
10) 11/12
11) 10/11
12) 1/12
