7.RP.A.3

Use proportional relationships to solve multi-step ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.

LESSON: SPORT STATS

What is the win percentage for each team?

The ability to use proportional relationships to solve multi-step ratio and percent problems is a skill that will benefit students in real world situations. In Sport Stats, Dave and Shannon are broadcasting live for Game 1 of the American East Division Unicycle Hockey Playoffs on the TV show, Ultimate Obscure Sports. During the broadcast, they planned to provide the viewers the win percentages for each of the four teams, but they don’t have the percentages! They only have the win-loss records for each team. The data provided is Shannon’s notes with the win-loss records for the four teams.
