Question

Round each mixed number to the nearest whole number and then estimate the difference. 18 9/11 - 8 3/8 10 11 8 9

Answer 1

Assuming that the last four numbers are answer choices, your answer would be 11

Explanation:

9/11 rounds up to 1, 1 + 18 = 19

3/8 rounds down, so you only have 8 for that one

19 - 8 = 11

Answer 2

Option (b) = 11 for difference between
`18 (9)/(11)` and
`8 (3)/(8)`

Explanation:

For rounding off each mixed number to the nearest whole number.

In this,
`18 (9)/(11)` is rounded off to the nearest whole number 19

`18 (9)/(11)=19`

and
`8 (3)/(8)` was rounded off to the nearest whole number 8

`8 (3)/(8)=8`

`18 (9)/(11)-8 (3)/(8)` = 19-8 = 11.

and the estimated difference was found to be 11
