Factoring – Using the Distributive Property. A factor is a number that can be divided into another number evenly. For example, the factors of 6 are 1, 2, 3, and 6. ... It means that a number outside the parentheses of an addition problem can be multiplied by each number inside the parentheses.
When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number:

. in our rational number the denominator is 1, and the numerator is 3
Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation:

. In this case, the numerator is 4, and the denominator is

.
We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span>

.
The first two are correct
