I assume the weights are 3*10^6 and 7*10^7
so the problem is 7*10^7 / 3*10^6
which is (7/3) * (10^7/10^6)
2.3333 * 10^1 (I assume the answer is desired in scientific notation since the problem was given in that form)
Ratio is (cake B weight)/(Cake A weight) = (7*10*7)/(3*10^6) = (7/3)*10^1
So cake B is (70/3) times as heavy as cake A.
