## Elementary Algebra

Let X represent the number of affected students. Now, let’s set up a proportion in which the first ratio is given, and it is $\frac{6}{10}$, and the other ratio represents the corresponding number of students. So, $\frac{6}{10}$ = $\frac{X}{15000}$ To solve this equation, we equate the cross products. 6 $\times$ 15000 = 10 $\times$ X 90000 = 10X Divide both sides by 10. X = 9000 9000 students would be affected at the university.
