What is called additive identity of rational numbers?

Answer:

An additive identity is a number y such that if I have a number x, the following should be true: x + y x Therefore, for the rational numbers y 0. Thus, 0 is the additive identity for the rationals. Hope this helps!

The additive identity of rational numbers is zero. The way you find it is you ask, A number plus what other number gets me the original number, or x+yx.

Have you ever replaced any of the brake lines? Does that right wheel lock up when it fails? If so, I'd suspect a bad proportioning valve. Disk brakes require much more pressure than drum brakes, so a proportioning valve reduces pressure to the drum brakes. Inlet pressure to the valve is 1,000 psi. Outlet pressure is 600psi. If it allows full pressure, it can lock up the drum brakes.

Hi, The additive identity of rational numbers is the fact that you can pick any rational number, add 0 to it, and get the IDENTICAL number as the answer. So ? + 0 ? or ? + 0 ?. I hope that helps!! :-)
