Rational numbers are numbers that can be expressed as a fraction or a ratio of two integers. They can be written in the form a/b, where a and b are integers and b is not equal to zero.
Examples of rational numbers include:
1/2
3/4
-2/5
0
Irrational numbers, on the other hand, cannot be expressed as a fraction or a ratio of two integers. They are non-repeating and non-terminating decimals.
Examples of irrational numbers include:
√2 (square root of 2)
π (pi)
e (Euler's number)
√3 - √2
In summary, rational numbers can be expressed as fractions or ratios, while irrational numbers cannot be expressed as fractions and have non-repeating decimals.
