To multiply fractions, multiply numerator by numerator and then denominator by denominator.

You may have to use what you know about division to help you solve the problem.

Remember: Use ratio tables to help you get a common number of items for each deal then compare prices.

What you do to the bottom, you gotta do to the top.
