Numerical Properties for 15
Determine characteristics for 15
- Rational
- Irrational
- Natural
- Whole
- Imaginary
Natural Number Test
Counting numbers > 0: 1,2,3,4,5,...
Since 15 is positive and a counting number, 15 is a natural number
Whole Number Test
Whole Numbers are positive numbers
They include 0
They have no decimal or fractional parts
Since 15 >= 0 and it is an integer, 15 is a whole number
Integer Test
Integers have no fractions or decimals
-5,-4,-3,-2,-1,0,1,2,3,4,5,...
15 is an integer
Rational Number Test
Rationals = a/b
where a and b are integers<
and b ≠ 0.
Since 15 is an integer or decimal from above, 15 is also a rational
Irational Number Test
They do not form a ratio between two integers
They are not an imaginary number.
Imaginary Number Test
Test for square root of a negative
Since 15 is not the square root of a negative number, it is not imaginary
