A class has 27 students. Fifteen are boys and the rest are girls. What is the ratio of girls to total students?

12 : 15
15 : 12
27 : 12
12 : 27

    Obviously there are 12 girls

    so ratio of girls : total
    = 12 : 27
    = 4 : 9

    The ratios should have been reduced in the answer choices.
