EQ: How do you set up and solve proportions when given a word problem? (with and without fractions)

Some rate problems you can solve in your head, making a table or by reasoning about the problem. See example below.

See video below to see how to solve the problem.

With the more difficult rate problems you can solve by setting up a proportion.

Proportions can have fractions in them. You will set up the proportion like you would with whole numbers. And cross multiply and then solve the equations. The fractions wil be complex fractions just like what we alrady learned.
