.75 - 1 = -0.25

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

Hence A

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

The answer is A.

Useful fraction property: 1/(a/b) = b/a
For example: 1/(2/3) = 3/2
And 1/(19/7) = 7/19

So, 1/(0.75 - 1) = 1/(-0.25) = 1/(-1/4) = -4/1 = -4


Alternatively, 1/(0.75 - 1) = 1/(3/4 - 4/4) = 1/(-1/4) = -4

= \(\frac{1}{-0.25}\)

=\(\frac{1}{-4}\)
