Write definition of whole number, natrual number,integer,rationalnumber,irrational number and real number
Answers
Step-by-step explanation:
i)a number without fractions; an integer.
ii)the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
iii)a whole number, such as 3 or 4 but not 3.5
iv)rational number is a type of real numbers, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number.
v)irrational number is a number that cannot be expressed as a fraction for any integers.
vi)real number is a value of a continuous quantity that can represent a distance along a line.
Answer:
Whole Number - The whole numbers are the numbers without fractions and it is a collection of positive integers and zero.
Example - 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,…
Natural Number - The set of numbers which does not have a 0, negative integer and fraction.
Integer - In Mathematics, integers are the numbers which can be positive, negative or zero, but cannot be a fraction. These numbers are used to perform various arithmetic operations, like addition, subtraction, multiplication and division.
Rational number - A rational number is defined as a number that can be expressed in the form p/q where p and q are integers and q ≠ 0.
Irrational number - Irrational numbers are the real numbers that cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.
Real number - Real numbers can be defined as the union of both the rational and irrational numbers. They can be both positive or negative and are denoted by the symbol “R”. All the natural numbers, decimals and fractions come under this category.
