In the first M games of a team's season, the ratio of the team's wins to its losses was 1:3. In the subsequent N games, the ratio of the team´s wins to losses was 2:3. 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 choices: A) 7:18 B) 3:7 C) 1:2 D) 2:5 E) 4:9
M = 4/9 of total games   N = 5/9 of total games   Wins = 1/4*4/9 + 2/5*5/9 = 1/9 + 2/9 = 1/3   Losses = 1 - 1/3 = 2/3   The ratio of wins to losses is 1:2.   The answer is 1:2.
