That attachment just defines a, b, and c.

5. MrsKelly

hmm Evaluate a – b + c

6. MrsKelly

sorry i not very good at this stuff

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.

8. Bladerunner1122

You follow?

9. Bladerunner1122

Say "yes" and I'll continue with my explanation.

10. MrsKelly

yes

11. Bladerunner1122

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

12. MrsKelly

oh well none of my answers say that.. do you make it smaller?

13. Bladerunner1122

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