HOW IS 1/(-2)³ THE SAME AS - 1/8? I understant that -2 x -2 x -2 = -8 but why does the entire fraction become negative?

I would think the answer would be 1/-8? Not -1/8? Are they the same thing?

This is GMAT study question.

yes, they are the same thing.

1/-8 = (-1)/8 = - 1/8

a fraction with one positive and one negatve number is negative

if x = 1/-8, -8x = 1, -x = 1/8, x = -1/8

if x = (-1)/8, 8x = -1, x = -1/8
