Storyboard Text

  • I'm going to tell you how to multiply fractions.
  • First you have to line up to two fraction next to each other.
  • For example, if you are multiplying 1/2 and 4/5 then you would line them up next to each other.
  • For example, the denominators of the fractions 1/2 and 4/5 are 5 and 2. You would multiply them together and you would get 10.
  • Then, you would multiply the denominators of the two fractions by each other.
  • If you remember the new denominator was 10 and the new numerator is 4. So the end product is 4/10
  • That would be your new denominator
  • Then you multiply the numerators of the two fractions by each other.
  • For example, the numerators on 4/5 and 1/2 are 4 and 1. You multiply them and you get 4. That will be your new numerator.
