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 tex2html_wrap_inline32 .

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 tex2html_wrap_inline32 has been reduced into the equivalent fraction tex2html_wrap_inline38 .

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.
