Why does every rational number have a additive inverse?
The rational numbers form an algebraic structure with respect to addition and this structure is called a group. And it is the property of a group that every element in it has an additive inverse.
How are integers and rationals numbers different?
All integers are rational numbers, not all rational numbers are integers. Rational numbers can be expressed as fractions, p/q, where q is not equal to zero. For integers the denominator is 1. 5 is an integer, 2/3 is a fraction, both are rational.
What is the relationship between real number and rational number?
Rational numbers form a proper subset of real numbers. So all rational numbers are real numbers but all real numbers are not rational.
What type of numbers are said to be in rational form and are referred to as rational numbers?
They are numbers which are written in the form p/q where p and q are integers.
How real numbers are divided into subgroups?
The main subgroup is the rational numbers. The set of irrational numbers is not closed with regard to addition basic arithmetical operations and so does not form a group.
What is a group of rational numbers?
A rational number is a number that can be expressed in fractional form.
Why does every rational number have a additive inverse?
The rational numbers form an algebraic structure with respect to addition and this structure is called a group. And it is the property of a group that every element in it has an additive inverse.
Are negative numbers rational numbers?
Some rational numbers are negative numbers. Rational numbers are those numbers that can be expressed as one integer over another integer, ie of the form p/q where p & q are both integers. For example: 1/3, 5/8, 36/5, -27/58

What numbers are The union of the rational and irrational numbers?
The real numbers.
What do rational and irrational numbers form?
The set of Real numbers.
What is a negative rational number?
Minus two.Some rational numbers are positive, some are negative. -9 is a negative rational number.
What are rational and rational numbers?
Rational numbers are numbers which can be written in the form p/q where p and q are integers and q > 0. Rationals is often used as an abbreviation to refer to the set of all rational numbers.
What are rational numbers and how are they used?
A rational number is a number that can be written in the form a/b, where "a" and "b" are integers and b is not equal to zero. For example, whole numbers are rational numbers.
