natural numbers, whole numbers, integer, rational number and real numbers
Step-by-step explanation:

Natural numbers starts from 1 to positive infinity. 11 is between 1 and positive infinity. Hence, it is a natural number
Whole numbers start from 0 to positive infinity. 11 is between 0 and positive infinity. Hence, it is a whole number
Integer consists of natural numbers, 0 and the negative of the natural numbers (...-2, -1, 0, 1, 2....)
11 is between these sets of numbers. Hence it is an integer
Rational numbers are numbers that can be written as a fraction.
11 can be written as a fraction. Hence, it is a rational number
Irrational numbers cannot be written as a fraction. So this option is wrong
Real numbers consists of natural numbers, whole numbers, integers and rational numbers.
Since 11 fall in one of these, it is also a real number
The sets to which the following number 11 belongs to are natural numbers, whole numbers, integer, rational number and real numbers
