Answer:

Yes, it is a rational number.

Explanation:

A rational number is a number that can be expressed in fractional form. A rational number consists of:

  • Integers - they can be expressed in form of
    \displaystyle{(a)/(1)} where a is an integer.
  • Fractions - obviously that they are in fractional form.
  • Repeating Decimals - they can be expressed in form of fractions as well.

Since the difference of 18 and 3 is 15 and the number 15 can be expressed as 15/1. Therefore, 15 or the difference of 18 and 3 is a rational number.
