Problem solving

On the last 3 day's I learning how to problem solve the problem was "The Teenage Mutant Ninja Turtles and Splinter are having a pizza party. Each person want's three pieces of pizza. Splinter has to order enough pizza for everyone. How many pizzas will he need what fraction of pizzas will each person get?" the hard part was solving the Question the easy part was that I knew the question I read the question twice then I knew what writ down, I written down three ways to do it.
