To calculate the percentage increase:

First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number


Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.

So in the problem:
First step:Increase = 1000 – 100
Increase = 900

Second:
% increase = 900 / 100 x 100%
increase = 900% increase

D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers
