The table organises the information for the cheeseburgers and fishburgers.
4/5 of the fishburgers sold and so 1/5 of the fishburgers was left. (These are fractions of the FISHBURGERS. When they are multiply with the fraction representing fishburgers, you will get the fractions of the total number of burgers. 2/14 of the TOTAL NUMBER was fishburgers left.
3/14 of the TOTAL NUMBER of burgers were left. So, 1/14 of the TOTAL NUMBER of burgers were cheeseburger left since 2/14 of the TOTAL NUMBER were fishburger left.
Then, we can find the fraction of the TOTAL NUMBER for cheeseburger sold.

But why is 168 1/14?
In my working, 168 is equated to 3/14 which is the fraction of the total number for cheeseburger sold.
