The ratio of numbers of days required is the reciprocal of the ratio of the number of hours worked per day. Think of examples with easier numbers: if you work on a project 4 hours a day, it will take you 2 times as long as if you work 8 hours a day.

ratio of hours worked per day: 7 3/4 to 8 = 31 to 32
ratio of number of days required: 32:31
number of days required by Bill's team: 15.5%2A%2832%2F31%29+=+%2831%2F2%29%2A%2832%2F31%29+=+32%2F2+=+16
