Algebra and Up: 

Question: Soren and his family share a lemon meringue pie that weighs 2 pounds. Soren takes a slice whose angle 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.
