Answer:
1 11/30
Explanation:
In order to add them up together, their denominators (in this case, 5 and 7) must be the same.
5 x 7 = 30
now that we figured out the common factor, we have to multiply the nominator as well to make it equal.
3 x 7 = 21
4 x 5 = 20
so that makes it 21/30 + 20/30. Now just simply add the nominators.
21/30 + 20/30 = 41/30.
Simplify it and the answer will be 1 11/30
