Question

What is the difference between an irrational number and a rational number. Give an example of each.

Answer 1

he word rational comes from"ratio". A rational number is a ratio of integers. By that I mean that any rational number can be written as:

a/b where a and b are integers and b is not equal to zero.

Irrational numbers are real numbers that are NOT rational.

Examples of rational numbers:

1) 2/9 = .222222222... with 2s going on forever. This is called a repeating decimal.

2) -11/5 = -2.2

3) 9475945637 / 474629506 is a ratio of integers, very big integers.

Examples of irrational numbers:

1) sqrt(2)

2) pi

3) cube root of 13
