Tony works at a pizza shop. He cuts two pizzas into eight equal sections each. Customers then eat 7/8 of each pizza. Tony says that 7/8 + 7/8 = 14/16, so 14/16 of all the pizza was eaten. Is Tony's addition correct? Explain.
No. If 14/16 of ll the pizza were eaten, this would be less than one whole pizza. If here are eight sections in each pizza, then people are eating eighths. All together they ate 14/8 or 1 3/4 pizzas.
