Malik and his friend are sharing two pizzas that are the same size. The first pizza was cut into 12 slices and the second pizza was cut into 8 slices. There are 10 people sharing so each person can get two slices of pizza. Malik is hungry and decides that he can get more pizza if he takes two slices from the first pizza instead of a slice from the first and a slice from the second. Show exactly how much more or how much less Malik will receive by taking both slices from the first pizza.
