Given: r is inversely proportional to s. If r = 16 when s = 3, then write the formula for the relation between r and s. a.r = s / 48 c.r = s / 16 b.r = 48 / s d.r = 16 / s

Given: r is inversely proportional to s. If r = 16 when s = 3, then write the formula for the relation between r and s.

a.r = s / 48
c.r = s / 16
b.r = 48 / s
d.r = 16 / s

It being inversely proportionate means that it should be r=n/s, n being any number, this eliminates A and C. To find your n, multiply s and r, getting n=sr=(3)(16)=48. Putting this into your equation, you get r=48/s, which is answer B.
