Problem
A small bottle of shampoo can hold 
milliliters of shampoo, whereas a large bottle can hold 
milliliters of shampoo. Jasmine wants to buy the minimum number of small bottles necessary to completely fill a large bottle. How many bottles must she buy?
Solution
To find how many small bottles we need, we can simply divide by . This simplifies to 
Since the answer must be an integer greater than 
, we have to round up to 
bottles, or
