Betsy won 5 games of Monopoly.  Helen won twice as many as Betsy and Susan won three times as many as Betsy.  Between them, how many games have they won?
Helen won twice as many games as Betsy's 5 so Helen won 2*5 = <<10=10>>10 games
Susan won three times as many games as Betsy's 5 so Susan won 3*5 = <<3*5=15>>15 games
When you combine their wins, together they won 5+10+15 = <<5+10+15=30>>30 games total
