Hi,

Mark had 3 times more marbles than Isabella.  Isabella had 2/3 as many marbles as Jack's highlight%28x%29 marbles 

Jack  highlight%28x%29  3

Isabella  %282%2F3%29x    2

Mark       2x             6     

       %2811%2F3%29x+=+T  Jack needs to have at least 3 marbles 

 11 or a multiple of 11 is the number of marbles there could have been.
