Answer :

Answer:

b) [tex]\frac{1}{2}[/tex] or 0.5

Explanation:

Let's see the actual product of the initial fractions

[tex]-\frac{4}{5}[/tex] * [tex]\frac{3}{5}[/tex] * [tex]-\frac{6}{7}[/tex] * [tex]\frac{5}{6}[/tex] = [tex]\frac{12}{35}[/tex]

= 0.3429 ≈ 0.34

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

Option A

(-1 * -1 * - 1) * [tex]\frac{1}{4}[/tex] = [tex]-\frac{1}{4}[/tex] or -0.25

Option B

(-1 * -1 * 1) * [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{2}[/tex] or 0.50

Option C

[tex]-\frac{4}{2}[/tex] * [tex]\frac{3}{2}[/tex] * [tex]-\frac{2}{5}[/tex] * [tex]\frac{5}{2}[/tex] = 3

Option D

[tex]-\frac{3}{4}[/tex] * [tex]-\frac{3}{4}[/tex] * [tex]-\frac{1}{5}[/tex] * [tex]\frac{1}{2}[/tex] = [tex]-\frac{9}{160}[/tex]

= -0.05625 ≈ -0.056

The initial fraction is [tex]\frac{12}{35}[/tex] or 0.34 & Option B is [tex]\frac{1}{2}[/tex] or 0.5.

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