Question

sally is taking a test
when she got her score it was 85% of 100% how many questions was on the test and how many did she get wrong

Answer 1

Answer:

There was 20 questions on the test.

She got 3 wrong.

Step-by-step explanation:

$\frac{85}{100} = \frac{17}{20}$

20 - 17 = 3

There was 20 questions on the test.

She got 3 wrong.

Answer 2

Answer: There were 20 questions and she missed three.

First of all, you need to simplify 85/100.

85/100 / 5/5 = 17/20.

Now that you know how many questions were on the test, subtract 17 from 20.

20 - 17 = 3

So in conclusion, the test had 20 questions and she missed three.

But this question doesn’t have enough info to be honest, if you multiply 17/20 with any number it’s still going to be 85%.
