DO YOU HAVE A COMMON DENOMINATOR?
(same bottom number = same size pieces)

NO: Continue below...



Change to equivalent fractions with a common denominator:
 Find a number divisible by BOTH denominators (such as the LCM: Least Common Multiple).
 Multiply both the numerator AND denominator of one fraction by the SAME NUMBER to get an equivalent fraction
with the common denominator.
 Repeat with the other fraction.
Go to the NEXT step...


3.

DO the Addition:

 Add the numerators
(to find the total number of pieces).
Keep the same denominator.
 Add the whole numbers (if any).
Go to the NEXT step...


4.

IS THE FRACTION IN LOWEST TERMS?

NO: Continue below...



Improper fraction:
(Top number is greater than the bottom
number.)
 Divide the top BY the BOTTOM;
 Write any
remainder as the numerator of a fraction using the same denominator.
Reduce the fraction:
 Divide both the numerator and the denominator by the same number.
 Repeat
until the only common factor is one.
