What is the role of 0 in rational numbers?
The role of zero(0) in rational numbers is when
Do whole numbers contain a set of rational numbers?
No.
What are rational nos?
Rational numbers are numbers that can be expressed as a ratio of two integers, a/b, where b is not zero.
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.
Can the sum of two rational numbers be zero?
Yes, it can.
Is 0 a rational number?
Zero is a rational number. Rational numbers are numbers that can be represented by the division of two integers. Zero is zero divided by anything besides zero, so zero is rational.
What is the role of 0 in rational numbers?
The role of zero(0) in rational numbers is when
Is the set of rational numbers closed under division and Why?
No. Zero is a rational number, but division by zero is not defined.
Do whole numbers contain a set of rational numbers?
No.
Does a real number contain the set of rational numbers?
No. A real number is only one number whereas the set of rational numbers has infinitely many numbers. However, the set of real numbers does contain the set of rational numbers.

Rational numbers are numbers that can be expressed as a ratio of two integers, a/b, where b is not zero.
What happens when you add subtract multiply and divide rational numbers?
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
What happens when a rational number is divided by an irrational number?
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Can rational numbers become fractions?
Yes. By definition, all rational numbers can be expressed as a ratio of two integers, the second of which is not zero. That is the fractional form of rational numbers.
What are rational numbers and how are they used?

Can the sum of two rational numbers be zero?
Yes, it can.
Are the set of rational numbers closed under division?
No, it is not. Division by zero (a rational) is not defined.
