What is the expression for 15 divided by some number?

• A. 15 - x
• B. 15 + x
• C. 15 / x
• D. x / 15

Answer: (C)

The expression for 15 divided by a certain number can be represented by the mathematical operation of division. In this case, when you divide a number, such as 15, by another number represented as "x," the correct form to express this operation is written as 15 divided by x, or 15 / x. This notation clearly indicates that you are taking 15 and distributing it evenly across the value of x, allowing for the calculation and interpretation of how many times x fits into 15. The alternatives, such as subtracting x from 15 or adding x to 15, do not represent a division operation and leave out the essential function of performing that calculation. Similarly, expressing it as x divided by 15 reverses the operation. Thus, the most accurate representation of 15 divided by some number is indeed 15 / x.
