Question

if three workers can make three widgets in three minutes, how many workers will it take to make 18 widgets in six minutes?

Answer 1

It will take nine workers

Explanation:

rate =
`(widgets)/(workersx time)`

`(3)/((3)(3))` =
`(1)/(3)`

rate x time x workers = jobs

`(1)/(3)` (6)(w) = 18

2w = 18 Divide both sides by 2

w = 9.

It will take 9 workers.
