Ratios can be used to show the relation between any quantity. They can be written in a few different ways.
EMILIE'S TEAM = 9 to 12 = 9:12 (read as 9 to 12) = 9/12 (read as 9 to 12; simplify by 3) = 3/4 (divide) = 0.75
GRANT'S TEAM = 10 to 15 = 10:15 (read as 10 to 15) = 10/15 (read as 10 to 15; simplify by 5) = 2/3 (divide) = 0.667
ANSWER: Emilie's team had a higher ratio of wins to losses. When setting up her team's ratio as a fraction of 9/12, it simplifies to 3/4, which is also 0.75. Grant's team only had a simplified 2/3 ratio, or 0.667. 0.75 is higher than 0.667.
