1

Answer 3

Leftover fraction is 1 - (1/3 + 1/4 + 1/6)  =  1 -  3/4  = 1/4 Answer

B. First pizza:-  1 - 1/3 = 2/3 had been eaten.
   Second pizza:-  1 - 1/4 = 3/4 was eaten.
   Third pizza:-   1 - 1/6  = 5/6 was eaten.
 C.  
 Total amount of pizza eaten =  3 - 3/4  = 9/4 = 2 1/4
 Amount eaten per person = 9/4 /  6 = 3/8 of a pizza
