Which are natural numbers, integers, rational numbers, irrational numbers and real numbers?
0, 1, 1/12, 1/16, 1/20

-Natural numbers are 0+ (no negative or decimals)
-Integers are any number that is not 0 or a fractional number (# with decimals/fractions)
-irrational numbers are numbers with decimals that go on forever and that do not repeat themselves
-rational number is any number that is predictable. So negative numbers, 0 and any number above 0 and decimals that are predictable (ex: 5.2)  or any repeating decimal not decimals that goes on forever bu does not repeat them self for example π-real numbers are any digit that is rational. This includes negative numbers and fraction.

so to answer your question

0: Natural number, real number, rational
1: Natural number, Integer, real number, rational
1/12: real number, rational
1/16: real number, rational
1/120: Real number, rational

Natural numbers are counting numbers (1,2,3,4,5...), not including 0

integers are natural numbers plus their negatives and zero (-3,-2,-1,0,1,2,3..)

rational numbers can be written in form a/b where b is not equal zero, terminating and repeating decimals can be written in this form

irrational numbers cannot be written in form a/b, they are non-terminating decimals

real numbers are rational+irrational numbers, not including imaginary numbers

basially
natural numbers are in integers which are in rational numbers which are not integers and those make up real numbers

so

0 is a whole number but that wasn't listed so it is an integer, rational number and a real number

1 is a natural number, an integer, a ratioal number, and a real number

1/12 is in form a/b, so it is a rational number and a real number

1/16 is also in form a/b, so it is a rational number and a real number

1/20 is also in form a/b, so it is a rational number and a real number
