what is 7/20-1/25
---------
It's an arithmetic problem.
Find a common denominator, then subtract.
The product always works, 20*25 = 500
7/20-1/25
= 175/500 - 20/500
= 155/500
= 31/100
==============
Don't waste time fretting about the LEAST common denominator.
Its only contribution is to waste time.
