When adding fractions, you need to have a common denominator, the bottom part of a fraction. Because one denominator is 14 and the other is 7, you must create a new denominator.

To create a new denominator, you can either reduce a fraction or multiply it by something, which is easier.

For this problem, we can convert 2/7's denominator into 14 instead of 7 by multiplying the fraction by 2/2:

2 x 2 = 4

7 2 = 14

2/7 has now converted into 4/14. Now, we can easily add.

-9/14+4/14 This can be rewritten as something more understandable.

4/14-9/14 We are now subtracting.

-5/14 This cannot reduce, so it is our answer.

I hope this helps!! Have an amazing day and let me know if you want more explanation ;)
