Yes - except that you need to specify ratios of INTEGERS. pi/2 is a ratio of pi and 2 but it is irrational.

The square root of any integer (except for a perfect square) is an irrational number. Other well-known irrational numbers are pi = 3.14159265... and e = 2.71828...

The number pi, which is approximately 3.14159265..., is an irrational number.

Pi is irrational. Irrational numbers, by definition, have no factors.

It can. pi / sqrt(5) = an irrational number. However, it doesn't have to be: pi / pi = 1.

The product of two rational numbers, as in this example, is always RATIONAL.However, if you mean 10 x pi, pi is irrational; the product of a rational and an irrational number is ALWAYS IRRATIONAL, except for the special case in which the rational number is zero.

Pi is irrational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.

There is no "last digit" of pi. Pi is irrational. Irrational numbers go in forever; like infinity

pi, in the mathematical term.

Yes. Except that it is pi, not pie.

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.

No they are not. The numbers Pi and e are irrational and are not radicals. There are many others.

Pi belongs to the sets of real numbers, transcendental numbers and irrational numbers.

They are infinite because pi is an irrational number

Consider pi and 4 - pi. 4 - pi + pi = 4, which is clearly rational. However, both pi and 4 - pi are irrational, as you can verify. plz to be lerning numburs Then consider pi + pi = 2pi, which is clearly irrational. The sum of two irrational numbers, therefore, may or may not be rational.

Yes. pi - sqrt(2) is irrational.

(pi) x (1/pi) = 1

2*Pi is an even irrational number.

no. irrational numbers are square roots of numbers that aren't square, pi, and some other numbers. irrational means it never ends.

Irrational number are NOT called surds. For example, pi is irrational but it is not a surd.Surds are a very small subset of irrational numbers.

Pi is an irrational number, meaning it never ends.

No, they are not. An irrational number subtracted from itself will give 0, which is rational.

No irrational numbers are integers. Pi is one example.

No; most real numbers are rational, actually, except for some, most famously 'pi'.

In general, no. It is possible though. (2pi)/pi is rational. pi2/pi is irrational. The ratio of two rationals numbers is always rational and the ratio of a rational and an irrational is always irrational.
