Question

1/6 of a ship's crew are engineers, 1/4 are stewards and the rest are soldiers. if there are 48 crew members in all, how many sailors are on the board of the ship?

Answer 1

`(1)/(4) + (1)/(6) = (6+4)/(24)= (10)/(24) = (5)/(12) \\ \\ 1- (5)/(12)= (7)/(12) \\ \\ 48* (7)/(12) =28`

Answer 2

`1/6 + 1/4 \\ = 2/12+ 3/12 \\ = 5/12 \\ \\ 1-5/12 \\ = 12/12 -5/12 \\ =7/12`


`7/12*48=28`

The answer is 28.
