Paul's pizzeria sells 45 cheese pizzas and 20 pepperoni pizzas each week. what is the ratio of cheese pizzas to pepperoni pizzas sold each week by paul's pizzeria? a. 3 : 1 b. 4 : 2 c. 9 : 4 d. 9 : 2

A ratio can be written 3 ways. 

1. a to b

2. a:b

3. a 
   
    b

Now when we are working with ratios we ALWAYS put the numbers the way the question asks. 

It says wat is the ratio of cheese pizzas to pepperoni pizzas sold each week, So we need to put the amount of cheese pizzas 1st, then the amount of pepperoni pizzas. 

45:20

45 to 20

 45 

 20 

Now we will SIMPLIFY. 

45 ÷ 5 = 9

20 ÷ 5 = 4

So, our new ratio would be C. 9:4.

Hope I helped ya!!
