Four friends are sharing a pizza. One friend eats half of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?
A. 1/5
B. 1/3
C. ¼
D. 1/6
We assume the pizza to be full representing 1. One friend eats ½ of 1=1/2
The remaining portion of the pizza=1-1/2=2/2-1/2=1/2
Three friends share equally ½ of the pizza=1/2÷3=12*13=1/6
Therefore, the Correct Answer is D.
