Vocabulary
• GCF- this is used to help us simplify a fraction. We must divide the numerator and denominator by the GCF.
• Mixed number- this is when we have a whole number and a fraction.
• Improper fraction- this is when we have a fraction that has a numerator larger than its denominator.

Multiplying Fractions
• To solve these types of problems you will be applying standard NS 2.1- multiplying fractions to solve a problem.
• Step 1- check to see if you can divide out common factors using the GCF. (cross cancel)
• Step 2- multiply the numerator.• Step 3- multiply the denominator.• Step 4- simplify (write your answer in a mixed
number if needed)
