A number that cannot be expressed as p/q, where pand q are both integers, is known as an irrationalnumber.

The word irrational in this sense does not mean unreasonable. It means not a ratio.

Is one and four thirteenths rational?

Yes. Any number that can be written as a fraction (with integers in the numerator and the denominator) is, by definition, "rational".


Is twenty over nineteen a rational number?

Yes. A rational number can be written as a simple fraction where the numerator and denominator are integers, given that the denominator does not equal 0.


A Set of numbers that can be written as fractions?

Those are the rational numbers. To be precise, you must be able to write the number as a fraction, with integers in the numerator and the denominator, to qualify as a rational number.


Why can every number be written as a fraction?

Every rational number, which includes integers, can be written as a fraction, with 1 in the denominator [bottom], or you could multiply the number by 2, and have this as the numerator [top], then have 2 in the denominator [bottom]. But when you say every number, the irrational numbers [such as pi, e, square root of 2, etc.]can not be written as a fraction.

What is the part of the fraction written below the numerator?

The denominator.


What is the number written above the line in a fraction?

That would be the numerator. The numerator is above the denominator. The numerator divided by the denominator would be equal to the quotient. So, numerator/denominator = quotient

Is 8 over 5 a rational or irrational number?

Long Answer: A rational number is a number that can be written as a fraction where both the numerator and denominator are both integers and the denominator does not equal 0. Since 8 and 5 are both integers, then this is a rational number. Short Answer: Rational


When the numerator and denominator have no common factor greater than 1 the fraction is written in?

The fraction then is written in its simplest form
