It's the same process as finding the least common multiple.
Example: 7/30 + 13/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
Since 210 is the lowest common denominator, we can proceed to add them.
7/30 = 49/210
13/42 = 65/210
7/30 + 13/42 = 114/210 or 19/35 in lowest terms.

How to change dissimilar fractions to similar fractions?
Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.
