...ART. 410.—The Terms of a proportion are the numbers compared. ART. 411.—The first and fourth terms are called the Extremes; the second and third terms are called the Means. ART. 412.—The Couplets are the equal ratios, hence, the first couplet must be the first and second...

...first and second terms make the first couplet; the third and fourth terms, the second couplet. 352. The first and fourth terms of a proportion are called the extremes; the second and third are called the means. EXERCISES IN FINDING RATIOS Find the ratios of the following couplets : The consequent...

...second term the consequent. Thus in the ratio a : b, a is the antecedent, and .b is the consequent. The first and fourth terms of a proportion are called the extremes, and the second and third terms the means. Thus in the proportion a : b = с : d, a and d are the extremes,...

...is to 6 as 10 is to 15 ; 4 : 6 = 10 : 15 is read the ratio of 4 to 6 equals the ratio of 10 to 15. The first and fourth terms of a proportion are called the extremes, and the second and third terms are called the means. Three numbers are said to be in proportion when...

...mean proportional or mean (Arithmetical, Harmonic, or Geometrical,) between the other two. In general, the first and fourth terms of. a proportion are called the extremes, and the second and third the means, the antecedents and consequents of the ratios preserving their...

...second term the consequent. Thus, in the ratio a : b, a is the antecedent, and b is the consequent. The first and fourth terms of a proportion are called the extremes, and the second and third terms the means. Thus, in the proportion о : b = с : d, a and d are the...

...of 6 to 10 forms a proportion, which may be written in the forms 3:5 = 6:10, f = ^ or3:5::6:10. 265. The first and fourth terms of a proportion are called the extremes, and the second and third terms the means. Thus, in the proportion 3 : 5 = 6 :10, 3 and 10 are the extremes,...

...the terms are smaller, but the ratio remains unchanged. 86 A proportion is the equality of ratios. The first and fourth terms of a proportion are called...extremes. The second and third terms are called the means. From observation the pupils will discover and state the conclusion that the product of the fourth term...
