If we want a definition, we can start by saying that fractional numbers are numbers that represent one or more parts of a unit that has been divided in equal parts.
The fractional numbers are figured out by two whole numbers (the fraction terms) that are separated by a horizontal line (the fraction line). The number above the line (the numerator) can be every whole number and the number below the line (the denominator) should be different from zero. Here are some examples of some kinds of fractions:
It may seem weird, but the answer is No. First of all because the definition tells us that fractional numbers are numbers that represent one or more parts of the whole. So, for instance, the number `10/2`, which is written as a fraction is not a fractional number, since it figures out number `5` and this one is not part of a whole. The number `sqrt 2 / 3` is also written as a fraction, but it is not a fractional number since the numerator is not a whole number.
