Answer 2

Answer:

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers.

This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers.

When expressed as a decimal, irrational numbers go on forever after the decimal point and never repeat.
