Proportion Word Problems Challenge

The video tutorial explains how to solve word problems involving proportions. It emphasizes the importance of labeling fractions correctly to ensure accurate placement of numbers. Three example problems are solved: calculating the cost of gasoline, determining car travel distance, and adjusting a cookie recipe for a large group. Each problem is solved by setting up a proportion, cross-multiplying, and solving for the unknown variable. The tutorial concludes with a summary of the methods used.

Why is it important to label the fractions in your proportions before solving?

• To make the problem more complex

• To ensure numbers are placed in the correct spots

• To make the problem look neat

• To confuse the solver
