Example: 1.5 is rational, because it can be written as the ratio 3/2 Example: 7 is rational, because it can be written as the ratio 7/1 Example 0.333... (3 repeating) is also rational, because it can be written as the ratio 1/3 Irrational Numbers But some numbers cannot be written as a ratio of two integers ... ...they are called Irrational Numbers. Example: π (Pi) is a famous irrational number. π = 3.1415926535897932384626433832795... (and more) We cannot write down a simple fraction that equals Pi. The popular approximation of 22/7 = 3.1428571428571... is close but not accurate.
