fractions and integers

[BW1989]

An integer is either a whole no. or its negative. A fraction can't be an integer. So how is it that 3 has been written as a fraction here?

Who told you that integers cannot be written in fractional form?

Integers are whole numbers and their negative opposites. Therefore, these numbers can never be integers: fractions. decimals.

I disagree with that. I would consider \(\displaystyle \frac{7}{1}\) to be a "fraction" and \(\displaystyle 3.0000\) to be a "decimal".
