Can you add two rational numbers and get a rational number?
Every time. The sum of two rational numbers MUST be a rational number.
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 0.62 a rational number?
Yes, 0.62 is a rational number. A rational number can be written as the quotient of two integers. 0.62 can be written as 62/100, which can be simplified to 31/50.
What is a number written as quotient of two integers where the denominator is not zero?
A rational number
How do you insert rational numbers between two rational numbers?
Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.
Is two over three a rational number?
Two over three can be expressed as a ratio (2/3), so it is therefore a rational number.
What is five and two sevenths as a rational number?
5 2/7 already is a rational number - you don't need to convert anything.
What must be subtracted from twice the rational number minus five by two to get two by five?
Twice the rational number 5/2 = 5From this, you need to subtract 4 3/5 to get 2/5.
Is Five is a rational number?
It can be expressed as the ratio of two integers in the form: 5/1.
Is the product of two rational numbers irrational?
The product of two rational numbers is always a rational number.
Is 3 times pi over two rational?
No; since pi is irrational if you multiply it by a rational number it is still irrational
Can you add two rational numbers and get a rational number?
Every time. The sum of two rational numbers MUST be 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 maximum number of rational number between any two rational numbers?
There are [countably] infinite rational number between any two rational numbers. There is, therefore, no maximum.
Is the fraction 22 over 7 irrational?
No, it is rational. A rational number is one which can be expressed as a ratio between two integers. Since 22 and 7 are both integers, then 22 over 7 is rational.
Does there exist an irrational number such that its square root is rational?
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
What kind of number do you get if you multiply two rational numbers?
You get a rational number.
