One.


Is twenty over nineteen a rational number?

Yes. A rational number can be written as a simple fraction where the numerator and denominator are integers, given that the denominator does not equal 0.


What is a requirement for a number to a rational number?

The requirement for a number to be a rational number is that it can be expressed as a ratio of two integers, where the denominator does not equal zero.


Is 8 over 5 a rational or irrational number?

Long Answer: A rational number is a number that can be written as a fraction where both the numerator and denominator are both integers and the denominator does not equal 0. Since 8 and 5 are both integers, then this is a rational number. Short Answer: Rational


Why does the definition of rational numbers state that b the denominator of the rational number ab cannot be equal?

I think it says a little more than that. b, the denominator of the rational number a/b, cannot be equal to zero because division by zero is undefined.


Is 100 a rational number?

Yes, 100 is a rational number.A rational number is any number that can be expressed as the quotient a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number.


A number that can be written in the form ab where a and b are integers and the denominator is not equal to zero?

Repeating decimal


What is the 15.125 it is a rational or irrational in math?

It is a rational number. The reason that it is rational is that you can represent it as a fraction, where the denominator (the number at the bottom of the fraction) is not equal to 0.So, for example, as we could write the number 15.125 as 15125/1000 then it is rational.


What is the ratio of 2 integers where the denominator doesn't equal 0?

That defines a rational number.


Why can't the denominator of the rational number A over B equal 0.?

Because division by 0 is not defined.


What is meaning of rational?

Mathematics a rational number is any number that can be expressed as the quotient a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number. The set of all rational numbers is usually denoted Q (for quotient).


Can any number serve as the denominator in a rational expression?

The math definition of a rational number is any number a/b so that both a and b are integers, except b ( the denominator) cannot be zero. So if you can manipulate the expressions to become this form, a/b, then it is the equavilent of a rational expression. Rational algebraic expressions are similar, except they contain variables. The same condition for the denominator must be true. The entire expression in the denominator cannot equal zero, but the variable might equal zero. Ex. a 1 / (x-1) .... x-1 cannot equal zero, which means that x cannot equal 1. Ex. b (1/3)/(1/4) can be simplified into 4/3 which is a rational number.
