Write a rational number that is not an integer.

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

It doesn't matter whether it's a whole number, a mixed number, a fraction,

or a decimal.

Here are a few:

1.6

3 and 3/4

2.71828

46 million and 1/2

negative 42

A rational is any number that can be written as a fraction and a integer is a whole number 0.86 = 43/50 so it is a rational, and not a whole number
