Fraction Check

Since 1/5 is a fraction, we use our long division decimal calculator to get 0.2

Natural Number Test

Counting numbers > 0: 1,2,3,4,5,...

Since 0.2 is not both positive and a counting number, 0.2 is not a natural number

Whole Number Test

Whole Numbers are positive numbers

They include 0

They have no decimal or fractional parts

Since 0.2 is not >= 0 and an integer, 0.2 is not a whole number

Integer Test

Integers have no fractions or decimals

-5,-4,-3,-2,-1,0,1,2,3,4,5,...

0.2 is not an integer

Rational Number Test

Check for integer or decimal

Rationals = a/b

where a and b are integers<

and b ≠ 0.

Since 0.2 is an integer or decimal from above, 0.2 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 0.2 is not the square root of a negative number, it is not imaginary
