6 / (4-11)

my answer was -87/-0.85714 which does not look right. Any help is appreciated

Your answer is not wrong, but it isn't "a fraction in simplest terms", because you've brought in a decimal approximation.

Go back a step, to

-87 / (-6/7)

which is where you were before you detoured into decimal-land.

Dividing by 6/7 is the same as multiplying by 7/6, so you can rewrite that as:

(-87)(-7) / 6

= 609 / 6

Factor of 3:

= 203 / 2
