Final answer:
Irrational numbers cannot be expressed as fractions or ratios of two integers, while rational numbers can. Irrational numbers have decimal representations that neither terminate nor repeat, while rational numbers either terminate or repeat. Examples of irrational numbers are π and √2.
Step-by-step explanation:
An irrational number is different from a rational number because it cannot be expressed as a fraction or a ratio of two integers. Irrational numbers are decimal numbers that neither terminate nor repeat. Examples of irrational numbers include π and √2. On the other hand, rational numbers can be expressed as fractions and have either terminating or repeating decimals. For example, 0.5, 1.25, and -3 are all rational numbers.
