If 45% of 400 respondents prefer option A, how many prefer A?

Explanation:
The main thing to grasp is how to apply a percent to a total. 45% means 45 out of 100, so 45/100 times 400 equals 0.45 × 400 = 180. A quick alternative is to note that 50% of 400 is 200, and 5% of 400 is 20, so 200 − 20 = 180. Therefore, 180 people prefer option A.
