Classwork - Tape Diagrams and Equivalent Ratios

Last week we used tape diagrams to learn about equivalent ratios and solve word problems. Tape diagrams are a great way to visualize ratio relationships. Below is an example of how we can use a tape diagram to represent and solve a problem.

Example: The ratio of the number of shoes Mr. E has to the number of sneakers Mr. E has is 5:2

If Mr. E has 25 shoes, how many sneakers does he have?

The five tapes represent the number of shoes Mr. E has. If we divide (25 ÷ 5)  then we know that each tape represents 5 shoes.

Now we can find out the number of sneakers Mr. E has, which is 10. Mr. E has 10 sneakers.
