Question

A cleaning crew can clean 5 offices in 6 hours how many offices can they clean in 12 hours

Answer 1

1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is
`(1)/(2)` of 12 (hours)
The opposite of
`(1)/(2)` is 2
6 (hours) multiplied by 2 (opposite of
`(1)/(2)` ) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours
