Drew purchased 3 books each with a different price, for $24. the cost of each book was a multiple of 4. what could be the price of the 3 books?

4,8, and 12 if you add them up you get 24.

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!!
