8

Explanation:

Lets use a calculator to give us something to compare to and decide if the compatible number solution is close enough.

By calculator#->7.6596....#

Rounding this up we have the value of 8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Rounding 5.23 we have 5
Rounding 40.06 we have 40

#40-:5 = 8#

This compares well.

5 is compatible with 40 as the division is very strait forward
