Any number that you can completely write down using digits is rational.

Let's try to write 2.51 completely with digits:

2.51That's it! We're pretty sure that 2.51 is rational.

The official math definition of a rational number is: A number that can be written

as a fraction made of whole numbers. Let's try and write 2.51 as a fraction

made of whole numbers:

251/100

We did it again! 2.51 is definitely rational.
