In the first M games of a team's season, the ratio of the team's wins to its losses was 3:1. In the subsequent N games, the ratio of the team´s wins to losses was 1:4. If M:N = 4:5, what was the ratio of the team's wins to its losses for all M+N games?
Choose the correct choice from the following answers: A) 1:2 B) 2:3 C) 3:4 D) 4:5 E) 5:6
M = 4/9 of total games   N = 5/9 of total games   Wins = 3/4*4/9 + 1/5*5/9 = 3/9 + 1/9 = 4/9   Losses = 1 - 4/9 = 5/9   The ratio of wins to losses is 4:5.   The answer is 4:5.
