Name a number that is a rational number, but not an integer.

Justify your response.

2.5 because rational numbers can be written as fractions, but integers written as fractions have to be able to be written over 1. For example 3 is an integer because 3 = 3/1. But 2.5 isn't an integer because 2.5 = 5/2.

3.1416 is a rational number.

It can be written as 31,416 / 10,000.

Since you can write it as a fraction with whole numbers, it's rational.

That's actually the definition of a rational number.

==> ANY number that you can write down completely

using digits is a rational number!
