If whole numbers or mixed numbers
appear in the multiplication problem,
they must be changed into fractions
before you can work the problem.

Write the steps for multiplying
mixed numbers in your notes:
• 1. Write mixed and whole numbers as
fractions (popcorn mixed numbers and
write whole numbers over one!)
• 2. Simplify early, if possible.
• 3. Multiply the numerators and then the
denominators!
• TAAA DAAAA!!!! Then you’re done! 
