Question

What is a reasonable estimate for the problem -3/2 times (-5 1/4)

Answer 1

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.

$\frac{-3}{2}\times \frac{-21}{4}$

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

$\frac{63}{8}$  

Whenever the same signs multiply the product are in positive.

Now, convert the resulting improper fraction into mixed.

$7\frac{7}{8}$.

Estimate value of 7 7/8 is 8.

Therefore, the reasonable estimate for the problem is 8.
