Math CentralQuandaries & Queries


Question from Linda, a student:

The ratio of girls to boys in class is 4:3. Total of 35 students, how many more girls than boys?

Thank you!


The fact that the ratio of girls to boys is 4:3 means that you can arrange the class into groups of size 7 with 4 girls and 3 boys in each group. How many groups are there? How many girls? How many boys?
