Question

8 cleaners can clean an office block in 3 hours. If two cleaners are off ill,how long will it take the rest to clean the block.

Answer 1

this is an inverse variation, so
8/n = 6/3
6n = 24
n = 4

or

I would take 24 cleaner-hours to do the job
so with 6 cleaners, it would take 24 cleaner hours/6 cleaners = 4 hours

Answer 2

there will be 3/4 as many cleaners, so it will take 4/3 as much time.

what is 4/3 * 3 ?
