Example
For example the number 5 is a whole number but if we change it to 5.2 or 5.5
then is is no longer a whole number.
1 is a whole number but if we add to it and it becomes 1.1 then that is
not a whole number. 9 is a whole number. 8.2 is not a whole number.
1/5 is not a whole number and nor is 1/2, but 6 is a whole number.
