The additive identity for rational numbers is 0. It is the only rational number such that, for any rational number x, x + 0 = 0 + x = x

A rational number is any number that does not have an infinite number of digits. So, as you wrote it, 2.8333333 is a rational number. However, if you meant the 3s to go on forever (as in the number 2.8 + 1/30), that would be an irrational number.

As much as, in these days of uncertainty, anything can be anything. As long as the constraints of a rational number are kept to, a rational number will always remain a rational number.

Yes, but only if the rational number is 0.

Only if the rational number is 0.

The answer depends on the ellipsis. If the .. is meant to indicate that the string of 5s continues without end ten it is a rational number.

yes, it is rational. In fact, it is an integer. It's prime factorization is 2^2 * 3 * 67 * 49801 If you meant .040040004, then yes, it is still rational. It can be written as a fraction as 40040004/100000000. any terminating decimal is a rational number.

YES Any rational number taken to any integer power is still rational. Now if you meant to refer to the irrational number Pi - which is approximately 3.14159..., then squaring it does not make it rational.

Any terminating decimal or repeating decimal is a rational number.-0.29292929292929 iseither a terminating decimal of the fraction -29292929292929/100000000000000or meant to be a recurring decimal (0.2929...) with the '29' recurring forever of the fraction 29/99Either way, it is a rational number.

It is a rational number. It can be written as a fraction.

yes

Is 12.05 a rational number or irrational number?

1.96 is a rational number

It is a rational number, as it can be written as a fraction.

a rational number is an integer when it does not have a decimal. An integer is a whole number, no parts of a number... -3, -2, -1, 0, 1, 2, 3 are all integers 2.14 and 6.789 are rational numbers but not integers. see the pattern?
