The result of which expression will best estimate the actual product of

b) or 0.5

Explanation:

Let's see the actual product of the initial fractions

* * * =

= 0.3429 ≈ 0.34

Now let's see the product of the fractions from options A - D

Option A

(-1 * -1 * - 1) * = or -0.25

Option B

(-1 * -1 * 1) * = or 0.50

Option C

* * * = 3

Option D

* * * =

= -0.05625 ≈ -0.056

The initial fraction is or 0.34 & Option B is or 0.5.

As such, Option B is the answer that best estimates the actual products of the fraction in the question
