The role of zero(0) in rational numbers is when
No.
Rational numbers are numbers that can be expressed as a ratio of two integers, a/b, where b is not zero.
Yes, it can.
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.
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.
The role of zero(0) in rational numbers is when
No. Zero is a rational number, but division by zero is not defined.
No.
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.
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.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Yes, it can.
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.
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.
No, it is not. Division by zero (a rational) is not defined.
