Solution
Step 1 ：The absolute change in the number of active monthly users from one year to the next can be calculated by subtracting the number of users in the previous year from the number of users in the current year. We need to calculate this for the years 2010, 2011, and 2012.
Step 2 ：The number of users in March 2009 is 202 million.
Step 3 ：The number of users in March 2010 is 448 million.
Step 4 ：The number of users in March 2011 is 678 million.
Step 5 ：The number of users in March 2012 is 902 million.
Step 6 ：The absolute change from March 2009 to March 2010 is \(448 - 202 = 246\) million.
Step 7 ：The absolute change from March 2010 to March 2011 is \(678 - 448 = 230\) million.
Step 8 ：The absolute change from March 2011 to March 2012 is \(902 - 678 = 224\) million.
Step 9 ：The final answer is: The absolute change in the number of active monthly users from March 2009 to March 2010 is \(\boxed{246}\) million, from March 2010 to March 2011 is \(\boxed{230}\) million, and from March 2011 to March 2012 is \(\boxed{224}\) million.
