The set of all fractional numbers is sometimes called the set of what?

The rational numbers. A rational number is defined as any number that can be written as a fraction, with integers in the numerator and the denominator. That includes the integers themselves, since, for example, 5 can be written as 5/1.The rational numbers.

What are examples of integers that is a rational number?

All integers are rational numbers.


Is 45 a rational number or an irrational number?

All integers are rational, since they can be written, for example, in the form 45/1.


Can integers be rational number?

Yes, they all are. A rational number is one that can be written as a fraction. Any integer can be written as a fraction by putting it on top (making the integer the numerator) and putting a "1" on the bottom.Yes. Absolutely EVERY integer is a rational number. A rational number is one that can be written as a RATI0 (fraction) of two integers. So for example, 7 is an integer but could also be represnted by 14/2 or 21/3 etc. Even 0 can be 0/7 or 0/91 etc.

Integers are aproper subset of rational numbers.


Is the number 1 a rational number?

All whole numbers (integers) are rational because they can be written as the number over 1. 1 = 1/1 so it can be written as a fraction so is rational.


An integer that is not rational?

The are an infinite number of rational numbers that are not integers, because a rational number is a number that is written as a ratio of two integers. For examble, 1/2 (i.e. a half) is a non-integer rational number. This form is generally called a fraction.
