Question

Select the rational expression that is equivalent to the given expression below. 4 over x - 3

Answer 1

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 4 over x - 3 is $\frac{4}{x-3}$.
