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  

Isabella  %282%2F3%29x    

Mark       2x                  

       %2811%2F3%29x+=+99

                x = 27, number Jack has. Isabelle has 18  and Mark 54



and... 27+%2B+18+%2B+54+=+99
