121 can be expressed as the ratio 121/1, where both numerator and denominator are integers, the denominator not being 0. That is the definition of a rational number.

We will now attempt to write121 completely, using digits:121We did it! So we're pretty sure that 121 is probably a rational number. Now we'll check it out according to the official mathematical definition:2). "A rational number is any number that can be written as the ratio of two whole numbers."We will now attempt to write 121 as the ratio of two whole numbers:121/1Again, we've succeeded! So 121 is definitely a rational number.
