ch. 6 pg. 380 reducing to lowest terms

Reducing to lowest terms by mutipling the numerator and the denominator by the same number.

ex. 3/5 to 6/10
3.2=6
5.2=10

reducing rational expressions can be done the same way.

a rational expression is expressed in lowest terms when the fraction can not
be put into lower terms except by the number 1. 1 does not change the value.

reducing to lowest terms a rational expression is completed the same way as with putting fractions in to the lowest terms by dividing the numerator and the denominator by the same number; then cancelling out the like terms.

ex. ab/ac to b/c the a's are the same; causes the a's to be cancelled out.
