Jada used 4 centimeters of tape to wrap 2 presents. How many presents did Jada wrap if she used 20 centimeters of tape? Assume the relationship is directly proportional.
We can set up a proportion to solve this problem. Let x be the number of presents Jada wrapped. We can then set up the following proportion: 4/2 = 20/x.
To solve for x, we can cross multiply and divide:
4x = 2 * 20
4x = 40
x = 40/4
x = <<10=10>>10
Therefore, Jada wrapped 10 presents using 20 centimeters of tape.
