11- is B

Step-by-step explanation: I know thins because I did eduenuty

B. 36 questions

Step-by-step explanation:

First, change the fraction to a percentage. Now you need to find 80% of 45. I use this setup here:

80/100 = x/45

To find x, or the number of questions you got correct, you will multiply 45 and 80.

45 x 80 = 3,600

You will then divide the product by the remaining number, which is 100.

3,600/100 = 36

x (questions you correctly answered) = 36

Other Way to Solve:

If that way of solving is too complicated, you can always do this:

8/10 x 45/1

8 x 45 = 360

10 x 1 = 10

360/10 = 36

17   x 256=4352

sorry if this is wrong, i'm new.
