With a proper fraction you always end up with less than a whole cake! Improper fractions are rational numbers where the numerator is greater than the denominator.

Can a fraction be an irrational number?

Irrational numbers can't be expressed as a fraction with integer values in the numerator and denominator of the fraction. Irrational numbers don't have repeating decimals. Because of that, there is no definite value of irrational numbers. Therefore, is irrational because it can't be expressed as a fraction.

What is every rational number?

Answer: Every rational number is a real number.

It can be defined as any number that can be expressed in the p/q form where q ≠ 0. We can also say that any fraction falls under the class of rational numbers, where the denominator and numerator are integers and the denominator is not equal to zero.
