The first term of a ratio is called the Antecedent, and the last term the Consequent. The antecedents in the preceding ratios are, therefore, 12, 19, and a, and the consequents 4, 9, and b. 233. Ratios may, therefore, be represented in the form of fractions, by making the antecedents the numerators, and the consequents the denominators; thus, 12 19, a-j.-g-, and-, express the ratios of 12 to 4, of 19 to 9, and of a to J. 234. A ratio is said to be of equality when the antecedent is equal to the consequent. Thus the ratio of 12: 12, or of a: a, is a ratio of equality. 235i A ratio is of greater inequality when the antecedent is greater than the consequent. Thus, The ratio of a+b: a, or of 12: 6, is a ratio of greater inequality. 236 A ratio of less inequality is when the antecedent is less than the consequent. Thus, The ratio of a: a--b, or of 6: 12, is a ratio of less inequality. Note.--It is evident that the ratio of equality may always be represented by unity. COMPARISON BY RATIOS. 237i If the terms of a ratio are both multiplied or both divided by the same quantity, the value of the ratio is not altered. The ratio of a: b is expressed by the fraction T. Let both b terms of this fraction be multiplied by n, and it becomes--. nb 4 The ratio of 4: 3 is expressed by the fraction-; and, if the o 12 4 terms of this fraction be multiplied by 3, it becomes-q-=k. Now, since the value of a fraction is not altered by multiplying both the numerator and denominator by the same quantity, a na T=-t, or the ratio a: b is the same as the ratio na: nb, and b nb the ratio of 12: 9 is the same as 4: 3. Thus the ratio of 16: 12, both terms being divided by 4, is the same as 4: 3. The ratio of 5: 7, both terms being multiplied by 3, is the same as the ratio of 1...Hide synopsis
