A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction.

$\frac{1}{2}$ ↔ .5
5 ↔ 5.0
$\sqrt{4}$ ↔ 2.0
-13 ↔ -13.0
0.38462... ( $\frac{5}{13}$ )

An irrational number is a number that is NOT rational. It's the complete opposite!

π ↔ 3.14159
.13133133...
$\frac{\sqrt{3} }{2}$ ↔ 0.86603...
- $\sqrt{5}$ ↔ -2.23607...
$\sqrt{5}$ ↔ 2.23607...

Hope this helps!!!
