It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

if the third num is a
first num is 1.1 a and second num is 1.25 a

now the question is what percentage 1.1a is of 1.25a
[spoiler]= 1.1a/1.25a*100 = 1.1*80 = 88%[/spoiler]
