Question

Brian bought a 15-pound bag of concrete. He spilled the bag into smaller bags that each holds 2 1/2 pounds. How many smaller bags did he fill?

Answer 1

Let's first convert 2 and 1/2 into an improper fraction, it will help later:

`2 (1)/(2) = (2*2+1)/(2) = (5)/(2)`

Now, just divide:

`(15)/( (5)/(2) )`

Which is the same thing as:

`15 * (2)/(5)`

Which you can simplify to:

`(30)/(5) = 6`

So your answer will be 6 smaller bags.
