Question

Need help with this math problem
On a 24 question math test, Nuno got 6 questions wrong. Nuno's score decreased by 30 points.

Drag the numbers to form the equation that represents how much Nuno's score changed by each incorrect answer.

( )( )= ( )

4, -4, 5, -5, 24, -24, 30, -30, 1/6, -1/6

Answer 1

I had to do several calculations to get the answer.

First I calculated how many points each incorrect answer decreased:

6 questions * x = 30 points => x = 30 points / 6 questions = 5 points / question.

Then I converted it in an equation of the kind:

( ) ( ) = 5

And concluded it was 1/6 * 30 = 5

So, the numbers must be placed on either of these two forms:

( 1/6 ) ( 30) = 5, or

( 30 ) ( 1/ 6) = 5.

Of course, both of them are correct answers.
