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

2.7 completely, using digits:

2.7We did it! So we're pretty sure that 2.7 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 2.7 as the ratio of two whole numbers:
