Ms. Quarles gave the same math unit test to all her classes. She grades 25% of the tests, which is 30 papers. How many students does Ms. Quarles have in total?(

Answer 1

30 papers represents 25% of the total number of students.

Let x be the total number of students.

0.25x = 30

x = 30 / 0.25

x = 120

Ms. Quarles has 120 students in total.
