Question

Javier rounded to the nearest half to estimate the product of 3 2/5 and -3 7/8. How do the estimate and the actual product compare

Answer 1

Answer:

17

Step-by-step explanation:

Answer 2

Answer:

The estimate is - 13 and the actual product is - 13.175.

Step-by-step explanation:

We have to first estimate the product of $3\frac{2}{5}$ and $-3\frac{7}{8}$ rounded to the nearest half.

Now, $3\frac{2}{5} \times (-3\frac{7}{8} )$

=$\frac{17}{5} \times(-\frac{31}{8} )$

= $-\frac{527}{40}$

= - 13.175

= - 13 (Rounded to the nearest half}

Therefore, the estimate is - 13 and the actual product is - 13.175. (Answer)

Note: Rounded to the nearest half means make twice the number then round it to the nearest integer and then divide it by 2.
