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 :

[tex]1/6 + 1/4 \\ = 2/12+ 3/12 \\ = 5/12 \\ \\ 1-5/12 \\ = 12/12 -5/12 \\ =7/12[/tex]

[tex]7/12*48=28[/tex]

The answer is 28.
[tex]\frac{1}{4} + \frac{1}{6} = \frac{6+4}{24}= \frac{10}{24} = \frac{5}{12} \\ \\ 1- \frac{5}{12}= \frac{7}{12} \\ \\ 48* \frac{7}{12} =28[/tex]
