Hi Asd,
Whole numbers cannot be fractions. One can convert a fraction into a whole number if the numerator is the same or larger than the denominator. For example, you provide 1/2 and 2/5 as examples. You will notice that both of these fractions have numerators which are smaller than their respective denominators. A fraction that is, for example, 4/4 does equal 1 which is a whole number.
If the numerator is larger than the denominator, you will have a mixed fraction, and one can readily see that a whole number is in the fraction, but you would need to convert the fraction into the whole number and its fractional remainder.
A good example of the above is 11/5, which if you notice would be expressed as a whole number of 2 and its fractional remainder.
