Question

Name the sets of numbers to which each number belongs.

Short answer

0 belongs to the sets of whole number, integer, rational number and real number.

Step-by-step solution

- Define different sets 

• The set $\left\{1,2,3,4,5,...\right\}$is called the set of natural number.
• The set $\left\{0,1,2,3,4,5,...\right\}$is called the set of whole number.
• The set $\left\{-3,-2,-1,0,1,2,3,...\right\}$is called the set of integer number.
• The set of rational number has numbers in the ratio form $\frac{m}{n}$, where m and n are integers and n is non-zero. The decimal form of a rational number is either a terminating or repeating decimal.
• A real number that is not rational is irrational. The decimal form of an irrational number is neither terminating nor rational.
• Combine sets of rational and irrational number is real number.

- Relationship between different sets

Following venn diagram shows relationship between different sets

Where, the symbols denote

N- Natural number

W- Whole number

Z- Integers

Q- Rational number

I- Irrational number

R- Real numbers

- Find the sets to which 0 belongs

As, 0 is a whole number. So, using above venn diagram, it is an integer, a rational number and a real number also.

Thus, 0 belongs to the sets of whole number, integer, rational number and real number.
