Answer:
The answer to your question is: I got 36 questions correct.
Step-by-step explanation:
number of questions = 45
grade = 80%
Solve this problem with a rule of three
45 questions ------------------- 100%
x -------------------- 80%
x = 80 x 45 / 100 = 3600 / 80
x = 36
You gotten 36 questions correct...
