All the fudge machines at a chocolate factory work at the same rate. Six machines working simultaneously can complete a big order in 22 hours. How many hours would it take to fill the order if the number of working machines decreased by factor of 4?

Answered by oobleck
1/4 the machines, so 4 times as long

The real question is -- how can six machines be decreased by a factor of 4?
