Answer 1

Both of the previous answers give the result as 4%.  However, that's the percentage of the cake that has been eaten.  The question asks what percentage of the cake is left, which is the remaining 96%.

Answer 2

__   =    ___    --------->  25x = 100 -------->  ____   x =    ____  ---------> 1x = 4 --------->  x = 4 %
