Answer:
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
