...the antecedents and consequents of the two ratios are respectively the antecedents and consequents of the proportion. The first and fourth terms are...the extremes, and the second and third the means. 197. When three quantities are in proportion, eg a : b = b : c, the second is called a mean proportional... | |

...proportion is sometimes written a : Ъ : : с : d, and is expressed by saying that a is to b as с is to d ; the first and fourth terms are called the extremes, and the second and third the means, of the proportion. If the third term be equal to the second, the proportion consists of three terms,... | |
