Question

There are 16 boys in an English class of 28 students. The ratio of boys to the total number of students in this class is typical of the whole school. There are 476 students in the school. About how many are boys?

Answer 1

In order to solve this problem, it is best to set up a proportion.  The proportion you would use is 16/28=x/476.  Cross multiply and then divide both sides of the equation by 28 to get x.  So, there are about 272 boys in the total of 476 students in the school.
