Add the following fractions: 3/20 + 1/2
To add fractions, you need a common denominator. In this case, the common denominator is 20.
3/20 + 1/2
To make the denominators the same, we can rewrite 1/2 as 10/20:
3/20 + 10/20
Now the denominators are the same, so we can simply add the numerators:
(3 + 10)/20
Simplifying the numerator gives us:
13/20
Therefore, 3/20 + 1/2 = 13/20.
