Question 1177096
<br>
B has 5/11 of the stickers; that is given directly.<br>
"The ratio of the number of stickers A had to the total number owned by B C D  was 1:7."  That means A has 1/8 of the stickers.<br>
"C had 1/3 as many as what A B and D had in total."  That means C had 1/4 of the stickers.<br>
C had 72 fewer stickers than B:<br>
{{{(5/11)x-(1/4)x = 72}}}
{{{(20/44)x-(11/44)x = 72}}}
{{{(9/44)x = 72}}}
{{{x = 72(44/9) = 44*8 = 352}}}<br>
ANSWER: Together they had 352 stickers.<br>
