Question

Lisa collected leaves from different trees for a science project. Every day for a week (7 days), she collected 7 leaves. How many leaves did she collect by the end of the week?

Answer 1

The total number of leaves that was collected by Lisa is the product of the number of days in a week and the number of leaves she collected per tree. This is shown below,
              (7 trees / week) x (7 leaves / 1 tree) = 49 leaves / week
Thus, Lisa collected 49 leaves in a week.
