Question

Malory got a 75% on her math test. To earn that score, she got 27 questions correct. Write an equation to find how many questions were on the test. Then solve

Answer 1

75% = 0.75

Let y = amount of questions answered correctly.

Let x = total questions on the test.

y = 0.75x

In this problem,

y = ?

x = 27

Plug our numbers into the equation we made above.

27 = 0.75x

Divide both sides by 0.75

36 = x

There were 36 questions on the test.
