In 5 minutes A will make one box. In 5 minutes B will make 5/7 of a box. Therefore the ratio of boxes produced in a given time is 1 : 5/7. If you multiply both terms of this ratio by 7 you will eliminate the fraction.

Note that the number of hours worked does not affect the ratio of boxes produced by A and B.
