No not really - Pi, is approximately equal to 3.14159 and is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers. Therefore cannot be expressed as a fraction.

Where high accuracy is not required, it can be taken as 22/7 - though as an approximation.

How do you write pi as an improper fraction?
Pi written as an improper fraction is 22/722 over 7
Is pi a prime number?
Pi is not prime nor composite, instead, it is what is called irrational (It can't be written as a fraction or whole number.) Because only whole numbers can be prime, pi is not prime.
Are all fractions rational numbers?
No. pi/2 is a fraction but, since pi is irrational, so it pi/2.
Is pi an irrational or a rational number?
Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = 3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI. Hence it is irrational See the links for proofs that pi is irrational.
What type of number cannot be written as a fraction where p and q are integers and q is not equal to zero?
Irrational numbers. A good example of this is pi. If you were to write out pi as a decimal, the digits after the decimal point would go on forever.
