This fraction chart can be used for students to find A, B, and C in percentage. It can also be used to answer these questions (if it is 2.5 by 2 inches): "How many square inches in the entire figure? How many square inches in C? What part of a square inch is B? How large is A when compared to C? How large is B when compared to A? Into how many quarter-inch squares could you divide the whole figure?" -Foster, 1921

A potentiometer instrument for measuring the potential (or voltage) in a circuit taps off a fraction of a known voltage from a resistive slide wire and compares it with the unknown voltage by means of a galvanometer. The sliding tap of the potentiometer is adjusted and the galvanometer briefly connected to both the sliding tap and the unknown potential; the deflection of the galvanometer is observed and the sliding tap adjusted until the galvanometer no longer deflects. At that point the galvanometer draws no current from the unknown source, and the magnitude of voltage can be calculated from the position of the sliding contact. This null balance method is a fundamental technique of electrical metrology.

Animals alive today are but a fraction of all that have been before our time. We are continually discovering species of animals long since vanished form the fact of the earth. The mammoth is notable the among fossilized remains that have been found frozen in the ice of northern Siberia. In France this drawing of a mammoth was found, evidently sketched by a man living in that time.
