If qr=13 and pt = 8 find qt

If q*r = 13 and p*t = 8 and we want to find q*t, then we must solve for q and t before multiplying them together.

We can divide qr = 13 by r to solve for q.

q = 13/r

We can divide pt = 8 by p to solve for t

t = 8/p

We multiply both of those equations together to get our answer.

q*t = (13/r) * (8/p) = 104/rp
