# Prepare a Presentation

Explain how you made a set of stars and triangles that has the same ratio of stars to triangles as the ratio in the given diagram.

Show how you made a double number line that represents equivalent ratios of stars to triangles.

Suppose you find the difference between the number of stars and triangles in the original set. Explain why making a set of stars and triangles with the same difference will not result in sets with equivalent ratios.

# Challenge Problem

Find the difference between each pair of aligned numbers on your double number line.

- What do you observe about the differences?
