Is 1000000 a rational number?
Yes
Is 1 over 2 A rational number?
Yes, 1 over 2 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers. In this case, 1 over 2 is the fraction 1/2, which meets the criteria of being a rational number.
Is 2 a rational number or irrational?
It is rational. It is a whole number so it cannot be irrational.
Is 2 and one third a rational number?
Yes. 2⅓ = (3×2+1)/3 = 7/3 which is of the form of one integer over another which is the form of rational numbers.
Is every rational number a natural number?
No. 1/2 is a rational number but it is not a natural number.
Are rational numbers whole numbers also?
Some are, but all are not. 2/1 is rational and whole but 1/2 is rational and not whole. So the answer is a rational number is not necessarily a whole number.
Is the sum of two rational numbers a natural number?
Sum of two rational numbers might be a natural number (1/2 + 1/2), but mostly it's just another rational number (1/2 + 1/3). So answer is no.
Is a rational number times a irrational number?
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Is a half a rational number?
Yes 1/2 is a rational number
How do you write 1 as a rational number?
Answer: 1 already is a rational number. If you want to get technical, you could write it as 1/1. Answer: Any integer is a rational number. No matter how you write it, it will still be a rational number. Answer: 10/10, 2/2, 3/3, 365/365, etc.
All rational numbers are integers?
A rational number is a number which can be expressed as the quotient of two integers, a quotient being the solution to a division sum. Therefore, 1/2, or one half, is a rational number, equal to 0.5. However, 1/3, or one third, is an irrational number, because if you had to write the number out as a decimal, the number would continue to recur. Therefore, all integers are rational numbers, but not all rational numbers are integers. EDIT: 1/3 is a rational number, whoever said it wasn't is a moron.
Is -1 1 2 rational number?
All whole numbers are rational numbers.
