Question

Vassil rounded to the nearest half to estimate the product of 5/8 and 8/9. How do the estimated and actual products compare?

Answer 1

The actual product is about 1 over 18 less than the estimate.

Explanation:

Answer 2

Answer: The comparison is mentioned below.

Explanation:

Since the nearest half of the fraction
`(5)/(8)` is 0.5 ( because
`(5)/(8)= 0.625` )

And, the nearest half of the fraction
`(8)/(9)` is 1 ( because
`(8)/(9)= 0.88`. )

Thus the product of the fraction estimated in the nearest half is,

0.5×1= 0.50

Actual product =
`(5)/(8)* (8)/(9)`=
`(5)/(9)`= 0.55

Thus, by taking nearest half answer is 0.50 while in simple product answer is 0.55 ( approx).
