    Ok, I see what you need to do. Before you can add or subtract you need to get each of the denominators to be the same. In this case, you should probably multiply each fraction to get the denominator to be 20.

    Alright, A is 4 and 1/5. To get the denominator to 20 we multiply both the "1" and the "5" by 4. So A is now 4 and 4/20. B is 2 and 7/20 so it's good as it is. C is 3 and 1/4. To get the denominator to 20 we multiply the "1" and the "4" by 5 so C is now 3 and 4/20. Recap: A= 4 and 4/20. B=2 and 7/20. C=3 and 4/20 a-b+c = 4 and 4/20

    Yes! In lowest terms it's 4 and 1/5
