Have I done this correctly? f is inversely proportional to d when d=50, f=256 Find value of f when d=80 Figured out a constant of 25/125 so f=50/1*125/25=250 Is thsi correct?

its incorrect since f is inversely proportional to d we have f=k/d where k is a constant now as f=256 when d=50 then k=fd=50*256 so value of f when d=80 f=(50*256)/80=160
f is inversely proportional to d ... ... where k is the constant of proportionality. substitute in the given values to solve for k ... ... finish the problem
ah I did d/k. Thanks.
