Question

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

Answer 1

The reasonable estimate for the problem is 8.

Explanation:

Given:

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

Now, convert the mixed fraction into improper.

`(-3)/(2)* (-21)/(4)`

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

`(63)/(8)`

Whenever the same signs multiply the product are in positive.

Now, convert the resulting improper fraction into mixed.

`7(7)/(8)`.

Estimate value of 7 7/8 is 8.

Therefore, the reasonable estimate for the problem is 8.
