All whole numbers are rational.

Question

All whole numbers are rational numbers. Is that true or false?

Answer 1

TRUE.  Any whole number may be expressed as the ratio of itself to 1, which is a ratio of integers, and hence rational.

Answer 2

True. If you make a whole number look rational, you would just place a 1 in the denominator:

3 = ³/₁

90 = ⁹⁰/₁

6149 = ⁶¹⁴⁹/₁
