Did you know?
Did you know that when categorizing numbers, they can be classified as either rational or irrational? Rational numbers are those that can be expressed as a fraction, while irrational numbers cannot be expressed in this way. Let's categorize a few numbers to understand better: 3.8‾3.\overline{8}3 is an example of a repeating decimal, and it falls into the irrational category. The number 8 can be expressed as a fraction, so it is rational. π (pi) is a non-repeating decimal, making it an irrational number. The fraction -147-14/7−7/14 is rational since it can be expressed as a fraction. The square root of 81 can be simplified to 9, a rational number. Finally, 2√2 is an irrational number since it cannot be expressed as a fraction.
