Question #0cf9a
1 Answer
Rational numbers have a finite or periodic decimal expansion, while irrational numbers have an infinite, non-periodic expansion
Explanation:
First let's answer the second part of the question:
But the larger the denominator, the smaller the number, so the first number is greater than the second. In mathematical notation you have
What we want then is rational numbers
are all rational because their decimal expansion is finite, and they are all between
Similarly, the number:
