How do you find the sum of dissimilar fraction?

Answer 1

Find a common denominator by finding the LCM of the dissimilar denominators and converting the fractions to equivalent fractions with the same denominator. Then add the numerators and put that sum over the common denominator. Reduce if possible.

Example: 1/5 + 1/6

The least common denominator of 5 and 6 is 30.

1/5 = 6/30

1/6 = 5/30

1/5 + 1/6 = 11/30
