Yes. A half multiplied by two gives one for example. Three by a third or 4 by a fourth or 5 by a fifth and so on, are all examples.

Is the difference of two rational numbers always rational?
Yes. This is the same as asking for one rational number to be subtracted from another; to do this each rational number is made into an equivalent rational number so that the two rational numbers have the same denominator, and then the numerators are subtracted which gives a rational number which may possibly be simplified.
Is one and one and a half an irrational or rational number?
1.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
The product of two rational numbers is -13by9 if one number is -26by7 find the ther number.?
The other is 7/18.
What is the difference between two rational numbers and one rational numbers?
Their count. Two in the first case, one in the second.
How do you prove the set of rational numbers are uncountable?
They are not. They are countably infinite. That is, there is a one-to-one mapping between the set of rational numbers and the set of counting numbers.
Is the product of rational numbers equal a rational number?
The short answer to your question: yes. This is one of the central axioms of math. If you'd like a bit more detail, try researching number theory.
Why the sum difference and product of 2 rational numbers rational?
A rational number is one that can be expressed as a/b The sum of two rational numbers is: a/b + c/d =ad/bd + bc/bd =(ad+bc)/bd =e/f which is rational The difference of two rational numbers is: a/b - c/d =ab/bd - bc/bd =(ab-bc)/bd =e/f which is rational The product of two rational numbers is: (a/b)(c/d) =ac/bd =e/f which is rational
How many different ways are there for the product of two irrational numbers to be rational?
Only one way: the numbers must be conjugates of one another.
Are whole numbers a rational number?
Yes. A rational number is one that you can write as a fraction a/b, with integers a and b (b not equal to zero). For a whole number, set b = 1. For example, 5 = 5/1, so it is a rational number.
Is the difference of two rational numbers always rational?
Yes. This is the same as asking for one rational number to be subtracted from another; to do this each rational number is made into an equivalent rational number so that the two rational numbers have the same denominator, and then the numerators are subtracted which gives a rational number which may possibly be simplified.
What is the product of one irrational number and one rational number?
Provided that the rational number is not 0, the product is irrational.
Is negative one hundred an one rational or irrational?
-101 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Is one and one and a half an irrational or rational number?
1.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
The product of two rational numbers is -13by9 if one number is -26by7 find the ther number.?
The other is 7/18.
When the product of two numbers is equal to one of the factors. what do you know about the other factor?
It is the number one.
What are the two numbers with aproduct of 12 and a sum of 23?
When dealing with numbers greater than one, the sum will never be greater than the product. This question has no rational answer.
Is one third rational or irrational?
1/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
