Review the table showing the percentage of contaminants remaining in a water sample after passing through each round of filters.Round% of Contaminants Left in Water Sample01001152230.3

Compare the percentage left after each round: 15 ÷ 100 = 0.15, 2.2 ÷ 15 ≈ 0.147, and 0.3 ÷ 2.2 ≈ 0.136. These ratios are approximately 14.9%, so about 14.9% of the contaminants remain after each round. The choice saying 14.9% are removed confuses the fraction remaining with the fraction removed.
