sturggling with fractions

Since you are adding a negative, you can take away the addition sign and the parentheses to make it look like this: -5/6 - 5/18

In order to subtract, you need to find a common denominator: 6 goes into 18, so 18 is your common denominator. You multiply the numerator and denominator of -5/6 by 3 so you can have a fraction with a denominator of 3: -5/6 * 3/3 = -15/18

Your new equation should be: -15/18 - 5/18

Now you subtract the numerators across and keep the denominator the same:

Numerator = -15 - 5 = -20

Your answer should be **-20/18**

If your teacher asks you to simplify your answer, you would divide by a multiple of both 20 and 18. The best number to divide by would be 2:

Numerator: -20/2 = -10

Denominator: 18/2 = 9

So your **simplified** answer would be **-10/9**

To find the **mixed fraction**, you would divide -10 by 9 and place the remainder as your numerator:

-10/9 = **-1 1/9**
