Rational numbers ---> any number written in the form of ratio a/b of 2 integer. **a,b **and** b** cannot be a **zero.**

Examples:

is a rational number because....

the numbers are written in a/b form and the decimals are repeating.

Example#2:

and are both rational because the 1st number repeats and the 2nd number terminates.However, **7.23242526**.......... -- > is not a rational number because the number does not repeat or terminate. This is an example of **irrational** number because the number never ends.

**Irrational Numbers ****---> **a number that cannot be put in the form of a/b where a,b is an element of Integers.

However, the decimal form of an irrational number will never end or repeat.
