Reducing Fractions: Example

Rule 10:
To reduce a simple fraction, follow the following three steps:

1.: Factor the numerator.
2.: Factor the denominator.
3.: Find the fraction mix that equals 1.

Example : Reduce the fraction .

Answer. Factor the numerator and factor the denominator and look for the fractions in the mix that have a value of 1.

You could still factor the numerator and the denominator, but it won't help because you won't be able to find the number 1. The fraction has been reduced into the equivalent fraction .

Now prove to yourself with your calculator that both fractions are equivalent. When you divide 81 by 72, you will get the same answer as when you divide 9 by 8.
