Answer:
12 games
Explanation:
Emma’s soccer team won 3 out of 5 games, which is a win rate of 60%. If Ella’s team wins at the same rate and has played 30 games this season, then Ella’s team has won 60% of 30 games, which is 18 games.
Therefore, the number of games Ella’s team has lost is the total games played minus the games won, which is 30 - 18 = 12 games. So, Ella’s team has lost 12 games this season.
