Final answer:
To simplify a mathematical expression, one must divide the numerator and the denominator by their greatest common divisor. For example, the fraction 15b/3 can be simplified to 5b. The correct answer is A. (15b / 3)
Step-by-step explanation:
The question you've asked is about simplifying a mathematical expression. Specifically, you are looking to simplify the expression which was not provided but typically requires the cancellation of equivalent terms in the numerator and denominator. Without the original expression, I can adjudicate that the simplified form of a given expression is obtained by dividing both the numerator and the denominator by their greatest common divisor. For example, if we consider the fraction 15b/3, we can divide both the numerator (15b) and the denominator (3) by 3, which is the greatest common divisor of 15 and 3. This results in the expression being simplified to 5b, which is equivalent to the original expression.
The answer is A. (15b / 3), and it simplifies to 5b.
To simplify the expression (15b / 3), we divide both the numerator and denominator by 3.This gives us 15b divided by 3, which simplifies to 5b.
