To add these fractions, you need to find a common denominator. In this case, the common denominator is 20 (since both fractions have denominators of 20 and 5).

So, let's rewrite the fractions with the common denominator:

7/20 + 3/5 = 7/20 + (3/5) * (4/4)
= 7/20 + 12/20

Now that the fractions have the same denominator, you can add them together:

7/20 + 12/20 = (7 + 12)/20
= 19/20

Therefore, 7/20 + 3/5 = 19/20.
