Answer 1

3/4-1/2=3/4-2/4=1/4
5/6-1/2=5/6-3/6=2/6=1/3
5/6-1/3=5/6-2/6=3/6=1/2
3/4-1/8=6/8-1/8=5/8
7/10-2/5=7/10-4/10=3/10
5/6-5/12=10/12-5/12=5/12
13/25-2/5=13/25-10/25=3/25
21/50-2/10=21/50-10/50=11/50
23/24-3/4=23/24-18/24=5/24
27/45-4/15=27/45-12/45=15/45=1/3
9/12-3/8=18/24-9/24=9/24=3/8
6/7-2/3=18/21-14/21=4/21
5/6-3/7=35/42-18/42=17/42
7/11-1/2=14/22-11/22=3/22
7/8-5/6=21/24-20/24=1/24
6/7-1/5=30/35-7/35=23/35

Answer 2

Let's simplify each of these expressions:

1. 3/4 - 1/2 = 1/4
2. 5/6 - 1/2 = 1/3
3. 5/6 - 1/3 = 1/2
4. 3/4 - 1/8 = 5/8
5. 7/10 - 2/5 = 1/10
6. 5/6 - 5/12 = 1/3
7. 13/25 - 2/5 = 3/25
8. 21/50 - 2/10 = 19/50
9. 23/24 - 3/4 = 2/24 = 1/12
10. 27/45 - 4/15 = 3/45 = 1/15
11. 9/12 - 3/8 = 6/12 = 1/2
12. 6/7 - 2/3 = 4/21
13. 5/6 - 3/7 = (35-18)/42 = 17/42
14. 7/11 - 1/2 = (14-11)/22 = 3/22
15. 7/8 - 5/6 = 21/24 - 20/24 = 1/24
16. 6/7 - 1/5 = (30-7)/35 = 23/35

Note: I have simplified the fractions to their simplest form where possible.
