Answer 2

1. 13/15

2. 4/13

3. 3/4

4. 1 1/18

5. 1/4

6. 3 1/6

7. 1

Explanation:

i will use the last one as an example, first reduce, so you would find the common denominator, in this case its 6, so you simplify 6/30 to 1/5. then you have 4/5+1/5, so since u have the same denominator, you can add the two numerators above the common denominator, so it would look like 4+1/5. then add the numbers. so you are left with 5/5 which in other words is 1. i hope this helps!
