What number produces a rational number when multiplied by 0.5?
Any rational number will do.
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.
Is a rational number multiplied a rational number rational?
Yes.
What numbers will produce a rational number when multiplied by?
The answer will depend on what it is to be multiplied by. Since this part is missing from the question, it is not possible to give a sensible answer.
Which number produces an irrational number when multiplied by?
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.
What number produces a rational number when multiplied by .5?
Every rational number does.
Which number produces a rational number when multiplied by 0.25?
0.45
What number produces a rational number when multiplied by?
1/5
What number produces a rational number when multiplied by 0.5?
Any rational number will do.
Which numbers will produce an irrational number when multiplied by 0.5?
Any irrational number multiplied by 0.5 will remain irrational. Any rational number multiplied by 0.5 will remain rational.
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.
What numbers will produce a rational number when multiplied?
Any number will be a rational number when multiplied.0 multiplied by any real number is rational and so it will produce a rational number when multiplied.If x is any non-zero number (rational or not), then since it is non-zero, 1/x is defined and x*(1/x) = 1 which is rational. So any non-zero number will produce a rational number when multiplied.Thus any number will produce a rational number when multiplied.
Will 0.54732814 produce a rational number when multiplied by 0.5?
The product of two rational numbers is a rational number. All decimal numbers that terminate or end with a repeating sequence of digits are rational numbers. As both 0.54732814 (as written) and 0.5 are terminating decimals, they are both rational numbers. As 0.54732814 is a rational number and 0.5 is a rational number, their product will also be a rational number.
What is the relationship between whole numbers and rational numbers?
-- Every whole number is a rational number. -- Any whole number divided by any whole number (except zero) produces a rational number.
Will 0.555 produce a rational number when multiplied by 0.5?
Yes. Since 0.555 and 0.5 are both rational numbers, their product will be rational.
Is a rational number multiplied a rational number rational?
Yes.
Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?
The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.
