Answer: The answer is 3 over 20.
Step-by-step explanation: On offer is 3 over 4 pizza.
Each person is given a slice that that is the same size as all the rest.
So the 3 over 4 pizza is split into 5 equally sized parts. Thus each of the 5 slices is 1 over 5 times 3 over 4 = 1x3 over 5x4 = 3 over 20 of a whole pizza.
