Question 14236
First, a percent is something over 100.  In mathamatical form, X/100.  Since you have 48%, you can change that to 48/100.  
You may think that is the answer, and in a way it is, but you must REDUCE.  Find the greatest common factor of 48 and 100.  You can also do it the easier way of dividing top and bottom by 2
48/100  =   24/50   =   12/25
You final answer should be 12/25
