A whole number is any number that is positive and is not a fraction or decimal. A whole number would be 8, 10, 44, 85, 35, 207. Whole numbers are exact and do not include anything between one number to the next.
A fraction is not a whole number. These are NOT whole numbers: -7, -4, 4/5, 1/3, 5.6, 8.9.
Hope this helps! :)
