1.14 Subtracting Fractions

SUBTRACTING FRACTIONS

Similar to adding fractions, fractions must have a common denominator (the bottom numbers must be the same) before being subtracted.

There are three steps to subtracting 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, subtract the top numbers (numerators) and place the result over the common denominator.
  3. Simplify the fraction (if possible).
