In a glee club, there are two times as many female than male members. How many female members are there if there are 18 members in the club?
How many groups are there? ** The club has a female group which has twice as many members as the male group, so there are 2+1=<<2+1=3>>3 groups in the club.
How many members are there per group? ** There are 18 members in the club, which means there are 18/3 = <<18/3=6>>6 members per group.
How many female members are there? ** Since the number of female members consists of two groups, then there are 6 * 2 = <<6*2=12>>12 female members in the club.
