    Change each percentage to a decimal and multiply by the number of pages. That tells you how many pages each person reads is a day. Then compare the numbers. For example: Allen: 15% = 0.15 0.15 * 56 = 8.4

    You can actually figure it out without doing any computation if you know what you're doing.
