1.13 Adding Fractions


There are three steps to adding fractions:

  1. Ensure that the bottom numbers (denominators) are the same. If they are not, change them so that they are the same (they have a common denominator).
  2. Once the denominators are the same, add the top numbers (nominators) and place the result over the common denominator.
  3. Simplify the fraction (if possible).
