Proportions Walk

Proportion #1 Write a proportion and solve At a football game at Cardinals stadium, one out of every three fans is a Cardinals fan. If there are 36,000 fans in the stadium, how many are Cardinal fans?

Proportion #2 Write a proportion and solve At an animal shelter, the ratio of dogs to cats is 3 to 2. If there are 48 dogs in the shelter, how many are cats?

Proportion #3 Determine whether the relationship between the two quantities shown in each table are proportional by graphing on the coordinate plane. Volume of a Cube Side Length (ft) Volume (ft3) 1 2 8 3 27

Proportion #4 Write a proportion and solve. Two out of five students in a class are boys. There are 30 students in the class, how many are boys?

Proportion #5 Determine whether the relationship between the two quantities shown in each table are proportional by graphing on the coordinate plane. DVD Rental Number of DVDs Cost ($) 1 7 2 9 3 11
