To quickly assess the difficulty of the text, read a short excerpt:
— is either the fraotion - of one unit taken m times, or it is n ft ^ the nth of m units. Hence, the numerator may be regarded as showing the number of units to be divided; and the denominator, as showing the divisor, or what part i* taken from each. 122. Proposition L — If we multiply the numerator of a fraction without changing the denominator, the value of the fraction is increased as many times as there are units in the multiplier. If we multiply the numerator of the fraction $ by 3, withou...t changing the denominator, it becomes $. Now, $ and f have the same denominator, which expresses parts of the same size ; but the second fraction, $, haying three times as many of those parts as the first, is three times as large. The same may be shown of any fraotion whatever. 123« Proposition II. — If we divide the numerator of a fraction without changing the denominator, the value of the fraction is diminished as many times as there are units in the divisor. If we take the fraction £, and divide the numerator by 2, without changing the denominator, it becomes £.
