Let's say Part 1 = 12, Part 2 = 35, and Part 3 = 15.

Each of the following as ratios reduced to lowest terms and as percentages to the nearest whole percentage point.

Part A: What is the part-to-whole ratio of Part 1 to the Whole? Ratio form = Percentage form = %

Part B: What is the part-to-whole ratio of Part 1 to Part 3? Ratio form = Percentage form = %
