When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number: $\frac{1}{3}$ . 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: $\frac{4}{x-3}$ . In this case, the numerator is 4, and the denominator is $x-3$ .

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