The document presents two ratio problems: 1) One involving sharing 4 pizzas among 10 people at a large table and 3 pizzas among 8 people at a small table. If the tables were combined, the ratio of pizza to people would be 7 pizzas to 18 people. 2) One involving coffee mixture A with a 2:3 milk to coffee ratio and mixture B with a 3:4 milk to coffee ratio. If the mixtures were combined, the ratio of milk to coffee would be 5:7.

1. ADDING RATIOS
Consider the two problems: Sharing Pizza & Coffee Problem.
Sharing Pizza
You are going to eat pizza with your friends. When you arrive you see that the restaurant has set
up one large table that seats 10 people, and a small table that seats 8 people. The server places
four pizzas on the large table and three pizzas on the small table. At each table, everyone shares
the pizzas equally.
If you were to combine the two tables, what will be the ratio of pizza to people? Explain your
thinking.
Coffee Problem
In mix A the ratio of milk to coffee is 2 : 3. In mix B the ratio of milk to coffee is 3 : 4.
What is the ratio of milk to coffee if the mixtures were combined? Explain your thinking.
