Answer:

The reasonable estimate for the problem is 8.

Step-by-step explanation:

Given:

The problem -3/2 times (-5 1/4)

Now, convert the mixed fraction into improper.

[tex]\frac{-3}{2}\times \frac{-21}{4}[/tex]

Then, multiply the numerator with numerator and denominators with denominator.

[tex]\frac{63}{8}[/tex]  

Whenever the same signs multiply the product are in positive.

Now, convert the resulting improper fraction into mixed.

[tex]7\frac{7}{8}[/tex].

Estimate value of 7 7/8 is 8.

Therefore, the reasonable estimate for the problem is 8.
