What is a Fraction?
A fraction is a number that shows part of a whole. In this fraction, “X” represents the
NUMERATOR, while “Y” represents the DENOMINATOR.

KEY
Adding and Subtracting FractionsWhen adding or
subtracting fractions, they must have a common denominator. In order to do this, you must find a number that both of the denominators in the problem can multiply to. When you find a number, you have to multiply the numerator by the same number you used to get the common denominator. Once you have found a common denominator, the problem should look something like this.
KEY
HINT
EACH OF THE FRACTIONS WILL BE MULTIPLIED BY A DIFFERENT NUMBER TO REACH A
COMMON DENOMINATOR
KEY
Multiplying Fractions
When multiplying fractions, multiply the first numerator by the second numerator. Do this with the denominators as well!
KEY
HINTMultiply across the top and then multiply
across the bottom.
Don’t forget to simplify your answer!
KEY
Dividing FractionsDividing is a little different. When dividing, be sure to
change any mixed number into an improper fraction. This will make it easier to divide. Take the second fraction and switch the numerator and the denominator (Flip the top number and the bottom number). Now you must multiply these fractions and simplify to get your final answer.
KEY
Mixed Numbers and Improper Fractions
Depending on how the question wants your answer to look like, your answer may be left improper or it may need to be changed into a mixed number.
