WebbRecurring Rational Numbers: The numbers that are not terminating but contain a single number or group of numbers that go on repeating them again and again for indefinite times are recurring rational numbers. For example: 4/9 = 0.444444444… 4/9 = 0.4 The following table shows various rational numbers that are often used in calculations: WebbMultiplication and Division of Irrational numbers. 1. The product of two irrational numbers can be rational or irrational number. √ 2 × √ 3= 6. Here the result is a rational number. 2. The result of the division of two irrational numbers can be rational or irrational number. √ 2 ÷ √ 3 =\ ( \frac { √ 2} { √ 3} \).
Rational and Irrational Numbers (Definition
Webb22 sep. 2016 · A rational number must have a repeating/terminating expansion. To see this, first we remove the integer part and assume that r = p q, where p < q. Next, we note that by multiplying the numerator by 10n for sufficiently large n, we can assume that p ( 10n) q in it's simplest form, is of the form s t where gcd (10, t) = 1. spongebob and the next day gif
