Answer:

Step-by-step explanation:

How many questions are on the exam?  Represent this by n.

Then 40% of n comes out to 12 questions, or more symbolically,

               0.40n = 12, after which we get n = 12/0.40 = 30

Answers:

(1)  0.40n = 12 is the desired equation.

(2) n = 30 is the number of questions on the exam.

(3) See above for explanations.
