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.

Are rational numbers closed under multiplication?
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
How do you order rational numbers when they come in percent forms?
Any percentage is simply a rational number, with the denominator of 100. So multiply them all by 100 and order the resulting rational numbers.
Which number can be multiplied to a rational number to explain that the product of two rational numbers is rational?
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
Are rational numbers whole numbers?
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
Is the difference of rational numbers a rational number?
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural numbers are rational.
What happens when you subtract rational numbers?
The answer is a rational number.
What happens when you multiply rational numbers?
The product is a rational number.
Use what you learned about opertions with rational numbers to complete the graphic organizer drscribe a process to perform each operation add subtract multiply and divide?
Not too sure of the question but in general rational numbers can be expressed as fractions whereas irrational numbers can't be expressed as fractions
What kind of number do you get if you multiply two rational numbers?
You get a rational number.
Why is division not closed for rational numbers give an example?
If a set is closed under an operation. then the answer will be a part of that set. If you add, subtract or multiply any two rational numbers you get another national number. But when it comes to division, it is closed except for one number and that is ZERO. eg 3.56 (rational number) ÷ 0 = no answer. Since no answer is not a rational number, that rational numbers are not closed under the operation of division.
What s happens when rational numbers are multplied?
The product of two rational numbers is always a rational number.
Can you subtract two rational numbers and get an irrational number?
Do you mean can we subtract one rational number from another rational number and get an irrational number as the difference? I'm not a mathematician, but I suspect strongly the answer is no. Wouldn't this imply that we can sometimes add a rational number to an irrational one, and get a rational number as a sum? That doesn't seem possible.Ans 2.It isn't possible. Proof :-Given two rational numbers, multiply the two denominators.Express each rational in terms of the common multiple.Algebraically add the numerators of the new rational numbers.Put this over the common multiple; there's the result expressed as a ratio.
What is the sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
What types of numbers can you multiply together to get a rational number?
You can multiply any pair of rational numbers as well as any irrational number and its reciprocal (or a rational multiple of its reciprocal. Thus pi * 3/7*(1/pi) is rational.
Can you multiply three irrational numbers to get a rational number?
no
When you multiply two irrational numbers the result is called what?
If you multiply two irrational numbers, the result can be rational, or irrational.
What two numbers multiply to get -144 but subtract to -7?
