Proportions as Equivalent Ratios
Proportions can be written as equivalent ratios, and since ratios look like fractions, you can use the same strategies you learned to calculate equivalent fractions to calculate proportions.
The simplest way to calculate a missing value in a proportion is to cross multiply then divide, as shown on slides 2-5. Use that strategy to complete the exercises on slides 6 and 7 from the starter.
