Not illustrated. 1856 Excerpt: ...$750: $100:: $180: ( ); the 4th term is jbund by Cor. 1st, Art. 249, to be 100 X 180 Hence, I gain $24 on every $100, or 24 per cent., since per cent. means on the hundred. The $24, in the solution above, is called the rate per cent, of the $180 to the $750. Though rate per cent. strictly means the number on a 100, yet as "$24 on a $100" conveys the same idea as "24 hundredths," and the latter is simpler and more general, it is the prevailing practice to consider the rate per cent. that one number is of another, as the number of hundredths it is of that other, and any per cent. of a number is so many hundredths of it. Thus, 7 per cent, of any thing is 7 hundredths of it. 2i do is 2A do. do. 100 do is 100 do. do. or the whole. Review.--252. What is the meaning of Percentage? What does it embrace? What are its principal applications? Solve the example. What does rate percent. mean strictly? 2. If I have 160 sheep, and sell 85 per cent, of them, how many sheep do I sell? Solution.--The whole flock (l60) being 100 per cent., the proportion is, 100 sheep: ( ) sheep:: 100 per cent.: 35 per cent.; the required term is 'fi x 3 = 56 sheep. Ans. 3. In a battle, 78 men are killed, which is 13j per cent, of the whole force; how many were engaged? Solution.--The whole force is 100 per cents; the slain (78) are 13j per cent.; hence, ( ) men: 78 men:: 100 per cent.: 13J per cent.; the required term is 78X100 3X.78X100 f--=-----= 585 men.. Ans. 13 40 Hence, there are three cases of percentage, according as the first of the two numbers compared, the second, or their-rate per cent., is to be found. All these cases can be solved by the GENERAL RULEFOR PERCENTAGE. Any two numbers are to each other, as the rates per cent, they represent of the same quantity....

The pages are unmarked but tanned with age (1856! ) and have some foxing, though nothing that obscures the text. Corners and spine ends are bumped. No dust jacket. Previous owners name is inside. The inside boards and end pages have some heavy foxing, and on the front end page, someone has done an arithmetic problem in inkwell-type black ink.
