Question

How do you add `-\frac { 6x } { 6} + \frac { 2x } { 6} + \frac { 2x } { 6}`?

Answer 1

`= -x/6`

Explanation:

In order to add or subtract fractions, there has to be a common denominator. In this case they are already the same, so we can write the three fractions as one fraction:

`-(6x)/6 +(2x)/6 + (2x)/6`

`=(-6x+2x+2x)/6" "` all like terms, so they can be added

`= (-2x)/6`

To simplify: divide both numerator and denominator by `2`

`= (-2xdiv2)/(6div2)`

`= -x/6`
