It is called a unit rate.

Like Fractions
Only after simplification. If you subtract numbers with the same denominator, you have to put the original denominator in the result, but you can later simplify this, in some cases. A simple example: 3/4 - 1/4 = 2/4. Same denominator, but this can be simplified to 1/2.
Yes. As both the numerator (2) and the denominator (500) are divisible by the same number (2), the fraction can be simplified to 1/250
Common denominator
You can't simplify it because the numerator and the denominator are not the same.
If the denominator can be divided by the same divisor as the numerator, it can be simplified. For example 6/24 = 1/4.
No, it is already in lowest terms - the numerator and denominator cannot be divided bya same number
5/8 can not be simplified because nothing in the numerator can be simplified by the same number as in the denominator. For example: 2/4 can be simplified to 1/2 because they both contain a 2.
They are called like or similar fractions.
In much the same way as a simplified ordinary fraction, a simplified algebraic fraction is one in which the numerator and denominator have no factor in common (other than 1). For example, (x + 3)/(x2 + 2x + 5)
There's no mathematical difference between them; they're the same value. They express the same ratio. In a simplified fraction, the GCF of the numerator and the denominator is 1. In an unsimplified fraction, that GCF is greater than one.
