A rational number is one that can be expressed as a fraction. For example 1.4 is a rational number because it can be expressed as 14/10. An irrational number is one which can not be expressed as a fraction. For example, $$\pi$$. What do you think - can $$\sqrt{2}$$ be expressed as a fraction or not?
