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
