Jared uses 24 tiles to cover the top of his desk. of the 24 tiles, ⅜ are blue. how many of the tiles are blue?

You need to work out what an eight  of 24 is:

 \frac{1}{8}  *  \frac{24}{1}=  \frac{24}{8} =  \frac{3}{1}  

Then you simply multiply 3 by 3 (as it is three eights not one) to get 9, so your answer is 9.

Hope i can you!
