Answer:
There were 30 questions on the test so she got 3 questions wrong.
Step-by-step explanation:
Given that:
Correct answers by Emma = 27
Percentage of correct answers = 90%
Let,
x be the total number of questions on test
90% of x = 27


Dividing both sides by 0.9

There were 30 questions on the test.
Wrong answers = Total questions - Correct answers
Wrong answers = 30-27 = 3
Hence,
There were 30 questions on the test so she got 3 questions wrong.
