Answer.
13 - 10 ==> . 3
25 - 10 ==> 15
55 - 10 ==> 45
If (13, 25, 55) are all reduced by ( 10 ) the result is.
.= ( 3, 15, 45 ).
The proportional increase each time is ( 3 ).
There are various presentations you might consider.. For a few numbers the above is fine.
For more numbers consider a grid:.
perhaps a Word or Excel Table.
