Question

How do you subtract `\frac { 20} { 33} - \frac { 30} { 33}`?

Answer 1

`-10/33`

Explanation:

`20/33 - 30/33 = (-10)/33`

because

`20 - 30 = -10.`

Answer 2

`-10/33`

Explanation:

Subtract the numerators keeping the same denominator

`20/33-30/33 = -10/33 = -0.dot3dot0`

Answer 3

See below.

Explanation:

All you really have to do is subtract the numerators if the denominators are the same, which they are. You wouldn't subtract the denominators though.
So, `20` `-` `30` `=` `-10`
So your final answer would be `-10` over `-33`.
