Answer this problem.
A test had 80 questions. Dianne got 90% of them correct. How many problems did Dianne get correct?

This... is a joke right?

And in case this isn't:

0.90 x 80 will give you your desired answer.

72 questions right unless my mental math blows now.
But what grade are you in, 3rd?


Equation.


0.90 x 80 = 72

If it was how many did the person get wrong. It would be.

.90 x 80 = 72
72 - 80 = 8

Homework help forums is that way<-

10 year old?

72 .

Yeah thanks. We are just now learning this in 7th grade. D:< And FYI, I'm usually able to answer these quite easily. Tis' why I have a 98 in math right now. I feel so insulted now.

I don't think it's possible to get something as simple as .90 x 80 wrong even with mental math.

Just take the overall number, and divide that into 100.
The number will come out as the points given Ex. 100/80 = 1.25
So you know you no each 1 answer correct is 1.25.
