Add the following fractions:
7/20 + 3/5
(1 point)
To add these fractions, we need to have a common denominator. In this case, the least common denominator (LCD) is 20, since both fractions have denominators of 20 and 5.
To find the sum, we first need to rewrite both fractions with the common denominator:
7/20 = (7/20) * (1/1) = (7/20)
3/5 = (3/5) * (4/4) = (12/20)
Now that both fractions have the same denominator, we can add them:
7/20 + 12/20 = (7 + 12)/20 = 19/20
Therefore, the sum of 7/20 + 3/5 is 19/20.
