Well you see, when you write something with a pencil, you leave behind tiny particles of graphite. Of course we see this as pencil markings becasue the particles are so tiny. Now after long periods of time, the graphite particles begin to fall off the paper depending on how old the paper is. This is why we see out old papers with faded out pencil markings. Now I could be totally wrong but if someone is willing to edit the response, feel free to do so.

What is the smallest number of pencils and erasers you can buy so that you will have the same number of each we have 12 pencils in a package and 10 erasers in a package?
To find the smallest number of pencils and erasers that you can buy to have the same quantity of each, you need to determine the least common multiple (LCM) of the package sizes. The LCM of 12 (pencils) and 10 (erasers) is 60. Therefore, you would need to buy 5 packages of pencils (5 x 12 = 60 pencils) and 6 packages of erasers (6 x 10 = 60 erasers) to have an equal number of both, totaling 11 packages.
