Which equation is not equivalent to the formula d = rt? r equals t over d r equals d over t t equals d over r d = tr

Question restated.

which is not equivalent to d = rt?

r = t/d

r = d/t

t = d/r

d = tr

If we divide both sides of the original equation by t, we are left with r = d/t, so we know that this is true. if we compare this, however, with the first item on the list, we can see that t/d does not equal d/t, so the first item on the list is the wrong one.
