Every terminating decimal has a finite number of digits, and all such numbers are rational. As another example, √2 = 1.414213…. is irrational because we can’t write that as a fraction of integers.

## Why is 17 a rational number?

In mathematics rational means “ratio like.” So a rational number is one that can be written as the ratio of two integers. For example 3=3/1, −17, and 2/3 are rational numbers. … The rational numbers are those which have repeating decimal expansions (for example 1/11=0.09090909…, and 1=1.000000…
