Assuming that you mean pi, and not pie, it is not a rational number.

The set of rational numbers is a field and this means that for every non-zero rational number, there exists a multiplicative inverse in the setand also, due to closure, the product of any two rational numbers is a rational number.

Now suppose 7*pi were rational.

7 is rational and so there is its multiplicative inverse, which is (1/7).

(1/7) is also rational so (1/7)*(7*pi) is rational

But by the associative property, this is (1/7*7)*pi = 1*pi = pi.

But it has been proven that pi is irrational. Therefore the supposition must be wrong ie 7*pi is not rational.

0It is rational number.

Any number times pi is irrational.

pi [not pie] is an irrational number.

No 22*pi is not a rational number

Not all number are rational. Pie is a number but is irrational.

No. Pie is potentially never ending. This makes it an irrational number.

No, Pi is an Irrational Number.

(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .

7 is a rational number and it is also a prime number

15/7 is a rational number

7 is the ratio of 7 to 1 ... a perfectly rational number.

their is no end to it... it goes on forever...

If you mean Pi as regards to a circle then it is an irrational number

There are an infinitely many amount. An integer is a whole number, e.g. the number 7. A rational number is one that can be written as a fraction. 7 is a rational number, because it can be written as 7/1. But the number 7/9 is rational, but not an integer because it is not a whole number.

Yes because 7 squared = 49 which is a rational number

6.5 is a rational number because it can be expressed as a fraction

7/8 is a rational number because only rational numbers can be expressed as fractions

is 5 over 7 a rational number

7 is a rational number because whole numbers, integers, and natural numbers fit under rational and 7 is a natural number:)Yes.

-7 is the ratio of -7 and 1 ... nice and rational.

-7 is a rational number

-7 is a rational number because it can be expressed as a fraction in the form of -7/1

Pie is always regarded as an irrational no. 12140.76 is rational as it is a terminating no. Irrational no. is always non-terminating and non repeating. example- Square root 2 , pie etc.

No, and nor is negative 5 pi.
