in the first m games of a team ' s season , the ratio of the team ' s wins to its losses was 1 : 2 . 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 ?
"m = 4 / 9 of total games n = 5 / 9 of total games wins = 1 / 3 * 4 / 9 + 2 / 5 * 5 / 9 = 4 / 27 + 6 / 27 = 10 / 27 losses = 1 - 10 / 27 = 17 / 27 the ratio of wins to losses is 10 : 17 . the answer is c ."
divide(add(1, 2), add(2, 2))
