find the difference 3/5 - 1/4  

 

To add or subtrack fractions, it's necessary first  

to write them with a common denominator.  

 

You can always find a common denominator by  

multiplying them together.  Sometimes there's a  

lower figure, though.  

 

                                                   3            1  

                                                 –––   —  –––   =  

                                                   5            4  

 

Multiply denominators to find a common denominator  5 * 4 = 20  

 

Thus, the fractions become as follows  

 

                                                  12            5           7  

                                                 –––   —  –––   =   –––  

                                                  20           20         20
