m is a certain fraction. When m is multiplied by its own denominator, the result is 16. What is the value of m's numerator?

A. 1/16

B. 1/4

C. 4

D. 16

E. The information given is insufficient to determine the value of the numerator.

We can let m = x/y, in which x is m’s numerator and y is m’s denominator. We need to find the value of x. Since when m is multiplied by its own denominator the result is 16, we have:

my = 16

(x/y) * y = 16

x = 16

Answer: D
