Well, if Peyton has two pizzas, and each are cut into 10 pieces each, there will be 20 pieces. Peyton and her friends eat 14 slices so we can write this as a fraction. 14/20 to make this fraction into a decimal we can times 20 by 5 to make 100 on the bottom. 14 times 5 is 70 so Peyton and her friends ate 0.70 (or 0.7) of the pizza! Hope that helps!! :)
