Answer:
1) 1 1/4
2) 2/3
3) 1 1/20
4) 5/8
5) 0
6) 2/9
7) 1 1/6
8) 1 1/4
9) 1/4
10) 7/15
Step-by-step explanation:
3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 1/4
2/6 + 1/3 = 2/6 + 2/6 = 4/6 = 2/3
4/5 + 1/4 = 16/20 + 5/20 = 21/20 = 1 1/20
1/4 + 3/8 = 2/8 + 3/8 = 5/8
2/4 - 1/2 = 2/4 - 2/4 = 0
5/9 - 1/3 = 5/9 - 3/9 = 2/9
1/2 + 2/3 = 3/6 + 4/6 = 7/6 = 1 1/6
3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 1/4
3/4 - 1/2 = 3/4 - 2/4 = 1/4
4/5 - 1/3 = 12/15 - 5/15 = 7/15
