Every rational number can be written as a repeating decimal:
Example: 1/3 = 0.3333333333...
Every rational number can be written as the ratio of two integers.
--------------------
Irrational numbers cannot be written as a repeating decimal:
Example: 2.1836903268.. endlessly without repeating any finite pattern

Rational numbers are numbers that can be written as fractions. In other words, rational numbers are fractions. Irrational numbers are numbers that cannot be written as fractions.
Sample Rational Numbers:
1.5 = 3/2
7 = 7/1
0.317 = 317/1000
Sample Irrational Numbers:
pi = 3.1415926535897932384626433832795 (and more...) It keeps going and thus cannot be written as a fraction.
Another number that you will see in later math courses is the number e.
e = 2.7182818284590452353602874713527 (and more ...) It keeps going and thus cannot be written as a fraction.
The square root of 2 is also irrational because it cannot be written as a fraction.
Is this clear?
