The football team ordered 2 pizzas, they didn't eat 1/12 of one pizza and 2/4 of the other. How much pizza was left?
kodGreya [7K]
To equally divide the pizzas, let's use a similar point to base on the remaining pizzas. On the first pizza 1/12 was not eaten an the other was 2/4. Use 12 as the base parts. 1/12 +2/4. 2/4 is equal to 1/2, so let's used 6/12 (also 1/2) to replace 2/4 to add both fractions. 1/12+6/12=7/12.
