compare the difference or the amount of change to the original starting number. i.e. 100 is the difference in each case but compare this to 200 in the first case and 800 in the second
100/200 = 0.5 or 50%
100/800 = 0.125 or 12.5%, the first has the faster rate of growth it grew by half it’s original amount
