Is 121 irrational or rational

Answer 1

1). This isn't a mathematical proof or definition, but it turns out that any number

that you can completely write with digits is rational. We will now attempt to write

121 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:

121/1

Again, we've succeeded! So 121 is definitely a rational number.
