how to you find the samllest division when reading a scale

2 answers

Is this the scale on a stick? Count the lines between large divisions. If there are 10 lines, for example, between 1 and 2 inches on a scale, then ech line is 0.1 inch (one line/10 lines = 1/10 = 0.1). If I have misinterpreted the question (you may have been talking about a balance) please clarify and repost.
how do you know how much each line is beause in certain parts it may equal to .02 or etc dependinq on the width
