Question

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

Answer 1

18 9/11 rounded to the nearest whole number is 19 and 8 3/8 rounded to the nearest whole number is 8 so 19 - 8 = 11

Hope this helps :)

Answer 2

The estimated difference is 11.

Explanation:

`18(9)/(11)` in simplified form is 18.81. This when rounded to whole number becomes 19.

Similarly,
`8(3)/(8)` in simplified form is 8.375 and when rounded to nearest whole number, it becomes 8.

Now, the difference will be :

`19-8=11`

So, the estimated difference is 11.
