Problem

What is the length of the pencil in the figure if the scale reads in centimeters?

A pencil lies over a ruler beginning with the same point. The ruler has 19 equally spaced markings. The even marks are labeled from 1 to 9. The tip of the pencil touches the marking that is centrally arranged between the seventh and the eighth markings.


Solution

We have to determine the length of the pencil placed next to a scale that reads in centimeters.


We can see that the numbers on the scale are in the increments of 1 and the lines halfway between two digits have values halfway between them.
