Question

Maris has a birthday party on Saturday. The girls at the party ate 7/12 of a large pizza and the boys at the party ate 2/3 of a large pizza. Without actually adding these fractions, can you tell if more or less than a whole pizza was eaten? Explain. ( Hint: Estimate using 0, 1/2, or 1)

Answer 1

Yes, more than a whole pizza was eaten. This is because if you simply look at the fractions, you will see that both are greater than 1/2 and so combined, they would be greater than 1. 

Answer 2

Yes because 7/12 is greater than half as well as 2/3
