Is o a rational number

    • How do you write a rational number?

      A rational number is any number that satisfies the following three criteria: It can be expressed in the form of a simple fraction with a numerator (p) divided by a (/) a denominator (q). Both the numerator and the denominator must be regular integers themselves. An integer is what we would normally call a "whole number" like 3 or 15. ... The denominator (q) cannot be zero.

    • How to identify a rational number?

      Few of the important properties are as follows: Whenever we multiply, add, subtract, or divide any two rational numbers the result is in always a rational number. Rational number remains the same when we divide or multiply the numerator and the denominator with same number. When we add zero to any rational number, we get the same number as the result. Rational numbers are closed under the subtraction, addition, and multiplication.

    • How can you tell a number is a rational number?

      Any number that can be written as a fraction or a ratio is a rational number. The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction.

    • Is a rational number sometimes a real number?

      Real Numbers include fractions (rationals), irrationals (such as pi), decimals, integers, basically everything other than Imaginaries. Since Real numbers contain more than Rationals, they are sometimes rational. √2 is a real number but it's not a rational number. 3 is a real and rational number.

      Example 4 – The Double of a Rational Number Derive the following as a corollary of Theorem 4.2.2. !!!! Solution: The double of a number is just its sum with itself. ! But since the sum of any two rational numbers is rational (Theorem 4.2.2), the sum of a rational number with itself is rational. ! Hence the double of a rational number is rational.

      Statement: There is no smallest positive rational number. Proof: For a contradiction, suppose the opposite, i.e., that there exists a smallest positive rational number, call it R. Since R is rational, we can write it as a/b, for positive integers a,b. Let R’ = a/(2b). R’ is also a ratio of integers, and hence rational.
