Getting to the Answer: To calculate the percentage of the voters in each district who had no opinion on fracking, divide the number of voters in that district who had no opinion by the total number of voters in that district. Choice (D) is correct because 3,205 ÷ 63,539 ≈ 0.05 = 5%, which is a lower percentage than in the other three districts that were polled (District A = 8%; District B = 7.6%; District C = 6%).
