In the class, \(\frac{5}{9}\) of the students have blue eyes. If 10 students have blue eyes, how many students are in the class in total?

Let us cross multiply.
5/9=10/x
9 x 10= 5x
90=5x
90 ÷ 5= 5x ÷ 5
18=x
So, the answer is 18. I hope this helped you, since I just learned cross multiplication last week.

The total number of students in the class is 18. This is found by setting up a proportion and solving for the total using cross-multiplication. Since 9 5 ​ of the students have blue eyes and that equals 10 students, we determined the total by calculating x = 18 .
