Question 513391: I need to know a number that is an real, rational, integer, whole and natural number
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! Rational numbers can be shown as a fraction: a/b
Note that b cannot = 0 because dividing by 0 is undefined.
However, b can =1, so all whole numbers are rational.
For example, 13 is a rational number: 13 = 13/1 = 26/2 = 39/3 etc.
All integers are rational.
All integers are whole numbers.
But not all rational numbers are whole numbers.
4/3 is a rational number.
So is 355/113, which is a very interesting number if you try it. (Hint: It is a rational approximation of a fundamental irrational number.)
.
Irrational numbers cannot be shown as a fraction.
The classic examples of irrational numbers are pi, e, and the sqrt(2).
.
Real numbers include both rational and irrational numbers.
Real numbers can be shown from -infinity to +infinity, including 0.
Real numbers are continuous.
This means there are infinitely many real numbers between any other two real numbers.
.
Finally, natural numbers are the ordinary counting numbers: 1,2,3...
.
Done.
