Answer

numerator, one, value

Work Step by Step

We know that if we are multiplying the numerator by the exact same thing as the denominator, then we are effectively multiplying by 1. After all, since the terms being multiplied into the numerator and the denominator are the same, the cancel each other out. Furthermore, multiplying by one does not change the value of the expression, so the final expression is equivalent to the original one.
