In a bag of 8 apples, 2 of the apples are green. In a bag of 4 apples, 1 is green. Is this a proportional relationship?
Talk About It
What is the first ratio, or fraction, you built?
What does the ratio represent? What is the second ratio, or fraction, you

equivalent? Is this a proportional relationship? Why or
why not?

Based on the problem, build the two ratios and draw them on the Fraction Squares worksheet. Explain whether the ratios are equivalent and write an equation to represent the equivalent ratios.
