Name the set(s) of numbers to which 0.16 belongs.

types of numbers:
natural numbers (counting numbers):
1,2,3,...
whole numbers: natural numbers plus 0:
0,1,2,3,...
integers: whole numbers plus the negatives of the natural numbers:
...,-3,-2,-1,0,1,2,3,...
real number:
any number that has no complex component,
a complex number is of the form a + bi,
where a and b are real numbers and i is the square root of -1,
so if you never seen a complex number, then all the numbers you have seen are real
rational number: any number that can be expressed as a fraction where the numerator and denominator are both real numbers
examples: 1, 1/2, 1/3, 27/100
irrational number: any number that can not be expressed as a fraction
examples pi, e, sqrt(2), sqrt(3)

Name the set(s) of numbers to which 0.16 belongs.

0.16 is a real number
0.16 = 16/100 = 8/50 = 4/25 is a rational number, it can be expressed as a fraction
