Answer:
4 over sixteen, or 4/16 is your answer.
Step-by-step explanation:
There are 2 pizzas, each of which contain 8 pieces. So, in all, there were 8 pieces. Eric ate two pieces from each pizza. So, 2+2=4. Thus, he ate four out of the 16 pieces. That brings us to our answer, 4/16.
I hope this helps you, have a wonderful day!
