How do multiplication and division of rational number relate to one another?
Division by a non-zero rational number is equivalent to multiplication by its reciprocal.
How are multiplying and dividing rational numbers related?
Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
Is zero a rational number but not an integer?
Zero is a rational number and an integer.
How do you use reciprocals to solve a division problem with rational numbers?
Division by any non-zero number is the same as multiplication by its reciprocal.
Is O a rational number?
A rational number can be expressed as a fraction or ratio of two integers. Zero is an integer. Therefore, zero is a rational number EXCEPT, that the denominator of a rational number cannot be zero. You can't divide by zero.

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.
Is a rational number closed for addition and for multiplication?
A rational number is not. But the set of ALL rational numbers is.

Are rational numbers closed under division multiplication addition or subtraction?
Rational numbers are closed under addition, subtraction, multiplication. They are not closed under division, since you can't divide by zero. However, rational numbers excluding the zero are closed under division.
Is zero a rational or irratiional number?
It is rational.
An example of a rational number?
Zero (0) is a rational number.
What is closing a rational number under addition And can you close them under subtraction multiplication and division?
Rational numbers are numbers that can be expressed as a fraction a/b where a and b are both integers and b is not equal to zero. All integers n are rational numbers because they can be expressed as the fraction n/1. Rational numbers are closed under addition, subtraction, multiplication and division by a non-zero rational. To be closed under addition, subtraction, multiplication and division by a non-zero rational means that if you have two rational numbers, when you add, subtract, multiple or divide them, you will get another rational number. For example, take the rationals 1/3 and 4/3. When you add them together, you get another rational number, 5/3. Same with the other operations. 1/3 - 4/3 = -1 (remember integers are rational, too) (1/3) * (4/3) = 4/9 (1/3) / (4/3) = 1/4
Is 0 a rational or irrational number?
Zero (0) is a rational number, because it is a whole number and an integer.
