    Answer:

    1 3/20

    Explanation:

    Find the lowest common denominator of both fractions, which is 20.

    2/5 = x/20. Find the value of x and that is 8.

    3/4 = y/20. Find the value of y and that is 15

    Add 8/20 and 15/20 and that gives you 23/20. This is an improper fraction so divide 23 by 20, which is 1 3/20
