Solve the equation.

This interactive application will help you hone your skills in adding fractions that do not have like denominators. Work the problems with paper and pencil first and then check your work using the interactive application. (You may note that the application shows how you can actually check your work on your own using paper and pencil.) For each problem you will need to enter the numerical values into the appropriate boxes. Click on the "play" button to begin. You may have to hit the "enter" key after entering a new equation in order to refresh the application.
