Laura answered 27 questions correct on a test on her test and scored 90%. How many questions where on the test?

Nadya [2.5K]

The number of questions in the test is 30

Step-by-step explanation:

Let's call the total number of questions in the test N.

We know that Laura answered 27 questions, and these 27 questions represent the 90% of the test.

Therefore, we can say that 27 is the 90% of N.

Re-writing the percentage as a fraction,

$90\% = 0.90$

This means that:

$0.90 N = 27$

And now we can solve for N to find the number of questions in the test:

$N=\frac{27}{0.90}=30$
