Ratios

Edward and Frank used ratios to help them with the prices for the bake sale. A ratio is a way to compare two numbers or quantities. When they were finding out prices of muffins, they used the ratio “1 muffin costs 30 cents.” They found equal ratios: “2 muffins cost 60 cents” and “3 muffins cost 90 cents.”
  1. Use your table or graph in Question 5 to name two ratios equal to the ratio “2 cookies for 25¢.”
The decorating committee plans to decorate the gym with crepe paper, ribbon, and balloons.

The committee measured the length and width of the gym in yards and the height of the booths in feet. When they went to the store, they found that ribbon is sold by the yard and the measurements on the packages of crepe paper are given in feet. One way to convert feet to yards and yards to feet is by making and using a graph. The students made a graph that compares feet to yards and yards to feet.
