Is four fifths a rational number?
It is a rational number.

No it is rational ( all integers are rational)

It is rational and, therefore, real.
Is four over three irrational?
No because 4/3 is a rational number
Is three over four a Real or rational or irrational or integer or whole or counting?
3/4 is classified as a rational number.

Integer, rational and irrational numner, real number
Can you add two irrational numbers to get a rational number?
Yes Yes, the sum of two irrational numbers can be rational. A simple example is adding sqrt{2} and -sqrt{2}, both of which are irrational and sum to give the rational number 0. In fact, any rational number can be written as the sum of two irrational numbers in an infinite number of ways. Another example would be the sum of the following irrational quantities [2 + sqrt(2)] and [2 - sqrt(2)]. Both quantities are positive and irrational and yield a rational sum. (Four in this case.) The statement that there are an infinite number of ways of writing any rational number as the sum of two irrational numbers is true. The reason is as follows: If two numbers sum to a rational number then either both numbers are rational or both numbers are irrational. (The proof of this by contradiction is trivial.) Thus, given a rational number, r, then for ANY irrational number, i, the irrational pair (i, r-i) sum to r. So, the statement can actually be strengthened to say that there are an infinite number of ways of writing a rational number as the sum of two irrational numbers.
Is the square root of four a real number or a rational number or an irrational number or integers or a whole number?
The square root of four is a real number because it is a non-negative number that can be expressed on the number line. It is also a rational number because it can be expressed as the fraction 2/1. In fact, it is both a real number and a rational number, as all rational numbers are also real numbers.
Which number is a irrational 317 25 0.6 33?
The given four numbers are all rational numbers
What is four fifths as a number?
Four fifths IS anumber.
Is four a rational number?
Yes, four is a rational number.
Is the square root of any whole number an integer ar an irrational number?
Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.
