The amount of pizza left in the pan = 3/4 Jack ate 1/2 of the pizza that was left in the pan. Then Amount of pizza ate by Jack = (3/4) * (1/2) = 3/8 Now it is required to find the amount of pizza ate by Jack from the whole pizza. Then Amount of pizza that Jack ate from the whole = 1 - (3/8) = (8-3)/8 = 5/8 So Jack ate 5/8 part of the total pizza. I hope this is the answer you were looking for. I have simplified the procedure for your understanding. Hope it has come to your help.
