Answer 2

1/7+4/7=5/7; 2/5+3/5=5/5=1; 8/9-5/9=3/9=1/3; 1/6+3/8=4/24+9/24=13/24;

5/6+2/7=35/42+12/42=47/42=1 5/42;

Answer 3

Let's simplify each of these expressions:

1. 1/7 + 4/7 = (1 + 4)/7 = 5/7

2. 2/5 + 3/5 = (2 + 3)/5 = 5/5 = 1

3. 8/9 - 5/9 = (8 - 5)/9 = 3/9 = 1/3

4. 1/6 + 3/8 = (4/24 + 9/24) = 13/24

5. 5/6 + 2/7 = (35/42 + 12/42) = 47/42

So, the simplified results are:

1. 5/7
2. 1
3. 1/3
4. 13/24
5. 47/42
