-3 is indeed a rational number. This is because we can write -3 in the form of a “fraction” as -3=-3/1 where -3 and 1 are both integers. This means that -3 is a rational number.

**Why is -3 a rational number?**

Recall that we say a number is rational if it can be written in the form \frac{a}{b} where ‘a’ and ‘b’ are both integers. This means that when a number can be written as a “fraction” with both the numerator and denominator being integers then the number is rational. Since -3 can be written as the fraction -3 = \frac{-3}{1} with both the numerator and denominator being integers we conclude that it is clearly rational.

Some other examples of rational numbers are -1, -6, 3/4, 0.5(=1/2), 3/2, etc.
