Question

three-fourths of the student body attended the pep-rally. If there were 1,230 students at the pep-rally, how many students are there in all?

Answer 1

To find the total number of students we need to determine the whole or 100% of the student body. We can set up a proportion to solve the problem:

3/4 = 1230/x

Let's cross-multiply:

3x = 4 * 1230

3x = 4920

Now divide both sides of the equation by 3:

x = 4920 / 3

x ≈ 1640

Therefore there are approximately 1640 students in total.

Hope this helped :)
