.75 - 1 = -0.25

So the expression becomes 1/(-0.25) = -100/25 = -4

Hence A

(A) -4

(C) 0.25
(D) 0.75
(E) 4

Solution:

We start by subtracting 1 from 0.75 in the denominator of 1/(0.75 – 1). This yields:

1/-0.25

Next we convert 0.25 to a fraction, so 0.25 = 1/4. This now gives us:

1/(-1/4) = 1 x -4 = -4
