Question

On the weekends, Brody teaches arts and crafts to kids. His Saturday class used a total of 45 pom-poms and 84 wooden craft sticks for the project. Now, Brody is preparing the supplies for his Sunday class. He needs 15 pom-poms.
If Brody uses the same ratio of pom-poms to wooden craft sticks, how many craft sticks will he need for Sunday's class?

Answer 1

Let x be the number of craft sticks. Using the same ratio:
45 pom-poms : 84 sticks = 15 pom-poms : x sticks.

So x = 84 * 15 / 45 = 84 / 3 = 28.

He will need 28 craft sticks.
