It isn't always possible to determine. For example, it is unknown whether the Euler-Mascheroni constant (0.5772156649...) is rational or irrational.Most famous numbers and constants are known to be rational or irrational. If it can be expressed as a fraction a/b where a and b are integers, it's rational.
If it can't be expressed as a fraction then it is an irrational number
Discuss how you can use the zeros of the numerator and the zeros of the denominator of a rational function to determine whether the graph lies below or above the x-axis in a specified interval?
Statement 1 is true but totally unnecessary. As integer is always a rational and you do not need to convert it to a fraction to determine whether or not it is rational. A negative fraction is can be rational or irrational. The fact that it is negative is irrelevant to its rationality. An integer number over a zero denominator is not defined and so cannot be rational or irrational or anything. It just isn't.
Integers are rational numbers, whether they are positive or negative.
"Rational" is an adjective and so there cannot be "a rational" (and certainly not "an rational"). Any answer would depend on whether the question was about a rational number, a rational person, a rational argument or "a rational" combined with some other noun.
When the rational number is expressed as a ratio in its simplest form, if the only factors of the denominator are 2 and 5, then the number has a terminating representation. Otherwise it has an infinitely recurring sequence.
Any integer, whether positive or negative, is a rational number.
A negative sign, by itself cannot affect whether or not a number is rational.
The decimal shows a repeating pattern. Repeating decimals are rational.
Any integer, whether it is positive or negative, is a rational number.
Yes - any integer, whether positive or negative, is a rational number.
The sign of a rational number does not depend on whether it is odd or even.
The sign of a number has no bearing on whether or not it is rational.
The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.
The composition of the rock will determine whether it is a rhyolite or an andesite.
rational * irrational = irrational.
Any positive number is always bigger than a negative number - whether they are rational or irrational.
false , i tried it on apex so its right
