Question

Vassil rounded to the nearest half to estimate the product of Five-eighths and StartFraction 8 over 9 EndFraction. How do the estimated and actual products compare? (Hint: use 18 for the denominator when estimating.) The actual product is about StartFraction 1 over 18 EndFraction greater than the estimate. The actual product is about StartFraction 1 over 18 EndFraction less than the estimate. The actual product is about StartFraction 1 over 9 EndFraction greater than the estimate. The actual product is about StartFraction 1 over 9 EndFraction less than the estimate.

Answer 1

Answer: The answer is about 1/18 less than the estimated answer.

Explanation:

1. Find actual answer

a.

=
`(5)/(8)` ×
`(8)/(9)`

=
`(40)/(72)`

b. simplify

=
`(5\\)/(9)`

2. Find estimate answer

a. Solve

=
`(5)/(8)` ×
`(8)/(9)`

≈
`(5)/(9)`

Answer 2

a
