Introduction

Chef Ma Mamia has a large order to fill; it’s the church’s annual pizza party and he needs to give enough pizzas to feed 500 hungry parishioners. You must find out the amount of pizza it will take if certain people eat certain amounts of slices.

When you are through with this webquest, you will be able to answer the following questions: How can slices of pizza relate to and help you better understand fractions? How do you multiply and add fractions using special things (pizzas)?

 

Task

You will decipher how many fractions make up a whole, and learn about adding and subtracting fractions by using pizzas.


Process

  1. On this link you must get a score of 80% or above to get the party participants satisfied

  1. MY QUESTIONS! Using the weblink below, find out the cost of a large pizza with 7 toppings of your choice and write it in the space provided on the worksheet here. Each large pizza has 16 pieces so you must figure out how many pizzas you need to order for 500 hungry parishioners if each parishoner eats 2 slices. Now multiply the number of pizzas you will need by the cost per pizza(Whew!)

Answers

The cost of a large pizza with 7 toppings is $21.75

For 1 slice of pizza per parishioner divide 500 by 16 which equals 31.25 pizzas

For 2 slices of pizza per parishioner, multiply 31.25 times 2 which equals 62.5 pizzas

To make sure each parishioner gets 2 slices you must round up from 62.5 pizzas and order 63 pizzas

The cost will be 63 pizzas multiplied by $21.75 per pizza which equals $1370.25
