Which Number Is Rational Apex?
In mathematics, rational numbers are those numbers that can be written as a fraction of two integers, where the denominator is not equal to zero. For example, 1/2, 3/4, and -5/6 are all rational numbers. Irrational numbers, on the other hand, are those numbers that cannot be written as a fraction of two integers. For example, π, √2, and √3 are all irrational numbers.
The Apex Learning Algebra 1 course includes a lesson on rational and irrational numbers. One of the questions in the lesson is "Which number is rational?" The possible answers are:
- π
- 0.36458121…
- 0.777…
- √5
The correct answer is 0.777…. This is because 0.777… is a repeating decimal, which can be expressed as a fraction of two integers. In this case, 0.777… can be expressed as 7/9.

Rational numbers are those numbers that can be written as a fraction of two integers, where the denominator is not equal to zero. Irrational numbers, on the other hand, are those numbers that cannot be written as a fraction of two integers.
- How can you tell if a number is rational or irrational?
There are a few ways to tell if a number is rational or irrational. One way is to try to write the number as a fraction of two integers. If you can do this, then the number is rational. If you cannot do this, then the number is irrational.
Another way to tell if a number is rational or irrational is to look at its decimal representation. If the decimal representation of a number is terminating, then the number is rational. If the decimal representation of a number is non-terminating and non-repeating, then the number is irrational.
