If the denominator (the lower part of the fraction) is the same you just add the numerators (the upper part) and place the result over the common denominator.

1/3

3/12 = 1/4

numerator is 8 denominator is 12

Convert the fraction to equivalent fractions with the same denominator, then the numerators can be subtracted: 11/12 - 3/20 = 55/60 - 9/60 = 46/60 = 23/30
