Question

The number 540 is the constant of proportionality, k, that relates the x and y terms of each of these ratios. Express k in terms of x and y.

Answer 1

The constant of proportionality, k, can be expressed in terms of x and y as k = 540/xy. This can be seen by dividing both sides of the equation 540 = x/y by xy to get k = 540/xy.
