Rational
Such numbers are called rational numbers.
The set of numbers that include the natural numbers, their opposites and 0 is called the set of integers.
These are called "rational numbers" (ratio -> rational), and can be represented by the set Q (integers are Z, natural numbers are N, real numbers are R, complex numbers are C). Any number that can be expressed as a fraction is a rational number. For example, 0.01 is a rational number, because it can be expressed as 1/100. Irrational numbers are often square roots of non-perfect squares (such as the square root of 2 or 7, but not 4 or 9).
Yes. The set of whole numbers (more usually called Integers) is a strict subset of the set of Real Numbers.
The are an infinite number of rational numbers that are not integers, because a rational number is a number that is written as a ratio of two integers. For examble, 1/2 (i.e. a half) is a non-integer rational number. This form is generally called a fraction.
Rational numbers.
Such numbers are called rational numbers.
No, they are not!
yes . Those numbers are called Integers .
They are called irrational numbers; numbers that can be expressed as a ratio of integers are called rational numbers. Some common irrational numbers are pi (3.14159...) and the square root of two.
because not all rational numbers are integers, recurring numbers, numbers to 1 decimal place and fractions are rational as well but all integers are rational
Yes. Natural numbers are the counting numbers we use. Integers however contains also the negative values. So yes, natural numbers are integers, but the converse is not true though: integers are counting numbers is false.
Integers
Whole numbers are called integers. There are positive integers, for example, 3, and its opposite, a negative integer, -3.
Whole numbers without decimals or fractions are called integers.
Numbers in the form of a/b, where a and b are integers, are called rational numbers. 3.1415926531 can be written as 31415926531/10000000000. So it is a rational number.
There are numbers which cannot be expressed as ratios of two integers. These are called irrational numbers.
