yes, it is a part of a ration.

In mathematics, a rational number (commonly called a fraction) is a ratio or quotient of two integers, usually written as the vulgar fraction a/b, where b is not zero.
Each rational number can be written in infinitely many forms, for example 3 / 6 = 2 / 4 = 1 / 2, but the simplest form is when a and b have no common divisors. Every non-zero rational number has exactly one simplest form of this type with a positive denominator. A fraction in this simplest form is said to be an irreducible fraction, or a fraction in reduced form.
The decimal expansion of a rational number is eventually periodic (in the case of a finite expansion the zeroes which implicitly follow it form the periodic part). The same is true for any other integral base above one, and is also true when rational numbers are considered to be p-adic numbers rather than real numbers. Conversely, if the expansion of a number for one base is periodic, it is periodic for all bases and the number is rational.
A real number that is not a rational number is called an irrational number.

Yup, 'cause a rational number is a number that can be turned into a ratio (fraction). 3 is the same as 3/1!

I'm Weriton, from Brazil.
I don't write in English very well...
Rational number is all number that can be written in form a/b, with a and b integer and b different of zero.
So, 3 can be written as 3/1.
Therefore, 3 is a rational number.
OK?
It forgives me for the errors of English...

A rational number is by definition a ratio of two numbers ... also called a fraction. 3 is not a fraction. Write is as 3/1 and it's rational.

Any number which can be expressed as p/q where p and q are integers is rational. Since 3 can be expressed in that format, it is rational.

Yes. Any integer of fraction is a rational number
Remember: 3 is actually a fraction too: 3/1

Yes. 3 = 3/1, a ratio.

I think so , I use it all the time for determining time, I count sets of 3 to fill my kettle, water jug & pouring things like milk & water. 6 sets of 1,2, 3, fill my kettle & 2 sets to fill a big glass, 1 set to fill a small one, I also buy things in sets of 3, cause there is just my G/F & me here & that means 2 for me & 1 for her.
