Exploring Basic Ratio Word Problems

The video tutorial covers solving word problems using ratios. It includes three examples: calculating the length of a shorter board piece given the ratio and length of the longer piece, determining the total number of students based on the ratio of boys to girls, and finding the total pages read by Theresa over two days using a given ratio. Each problem is broken down step-by-step, demonstrating how to use ratios to find unknown quantities.

If a board is cut into two pieces with lengths in the ratio 2:5, and the longest piece is 85 inches, what is the length of the shortest piece?

• 50 inches

• 40 inches

• 34 inches

• 60 inches

In the first example, how many units does the longest piece have?

• 5 units

• 7 units

• 2 units

• 3 units
