1.10 Simplifying Fractions


Simplifying a fraction is writing a number in its most basic form. Sometimes fractions involve very large numbers in both the numerator (top number) and in the denominator (bottom number). As a general rule, it is easier to work with simpler fractions. So, always simplify.

There are three basic rules for simplifying fractions:

  1. Any number written over 1 is that number.
  2. A fraction can be simplified if the top and bottom numbers can both be divided by the same number, without leaving a remainder.
  3. If the top number is larger than the bottom number, and neither number can be divided by the same number, divide the top number by the bottom number.
