Algebra and Up:
Question: Soren and his family share a lemon meringue pie that weighs 2 pounds. Soren takes a slice whose angel measures 40°. How much does the remaining pie weigh?
Answer: 17/9 pounds
Solution: After Soren takes a 40° slice, there are 320° of pie left. That’s 320 ÷ 360 = 8/9 of the pie, and 8/9 of 2 pounds is 17/9 pounds of pie.
