Tip


  1. Remember that when simplifying fractions, you just divide top and bottom by a common factor.
  2. It will require fewer steps of working if you pick large factors, for example dividing both numbers by their highest common factor will get you the answer in a single step.
  3. However, it is often easier to calculate if you pick small factors like 2, 3, or 5.
  4. It's up to you which way to do it.
