tony ordered 3 pizzas for a party. each person at the party ate 1/6 of a pizza. there was no pizza left over. how many people were at the party?
Let N be the number of people at the party and P be the number of pizzas ordered.
P = 3
N/6 = P
N = 6P = 18
Check: 18 people eating 1/6 pizza each is 3 pizzas.
