Practice admits of a great variety of rules, the multiplication of which serves little else than to confuse the mind of the scholar. The most useful are here given, and all that are actually necessary for the man of business; but the scholar who wishes to pursue his studies beyond this elementary treatise, will find the subject amply treated of in the large Arithmetick of PIKE. CASE I. To find the value of any number of pounds, &c. when the price of one pound is an aliquot part of a dollar. RULE. As the value of any number of pounds at one dollar a pound, will be just so many dollars as there are pounds therefore, call the pounds dollars, and divide them by such an aliquot part as the price is of a dollar, the quotient will be the answer in dollars. 248 How do you find the value of any number of pounds, &c. when the price per lb. is an aliquot part of a dollar? To find the value of any number of yards, &c. when the price of one yard is an aliquot part of a pound. RULE. Call the number of yards so many pounds, and divide them by such an aliquot part as the price is of a pound, the quotient will be the answer in pounds. 3. What is the value of 500 4. What will 37 yards of bushels of potatoes, at 2s. 6d. a sheeting come to, at is. 8d. a bushel? yard? Ans. £62 10s. Ans. £3 2s. 6d. 5. What will be the value of 6.

How do you find the value of a certain number of yards, when the price of one is an aliquot part of a pound? CASE III. To find the value of any number of pounds, &c. when the price of one pound is an aliquot part of a shilling. RULE.-Call the given number of pounds so many shillings, and divide them by such an aliquot part as the price is of one shilling, the quotient will be the answer in shillings. To find the value of any number of yards, &c. when the price of one yard is shillings, or shillings, pence and farthings, and not an aliquot part of a pound. RULE. Write down the given number of yards, &c. and call them so many pounds. Divide the given price into aliquot parts, either of a pound, or of one another; then divide by the several aliquot parts, and the sum of the quotients will be the answer in pounds. EXAMPLES. 1. What will be the value of 36 2. What will 72 yards of Cassiyards of silk vesting, at 7s. 6d. a mere come to, at 15 shillings a yard? yard? S. £ 5=136 £54 Ans. 250. How, when the price of a pound is an aliquot part of a shilling? 3. What is the value of 139 gal-] lons of wine, at 9s. 10d. a gallon? Ans. £68 6s. 10d. 5. What will 146 yards of broad 4.

Ans. £67 10s. CASE V. To find the value of any number of pounds, &c. when the price of one pound is pence, or pence and farthings, and not an aliquot part of a shilling. PULE.-Write down the given number of pounds, &c. and call them shillings. Divide the given price into aliquot parts, either of a shilling, or of one another; then divide by the several aliquot parts, and the sum of the quotients will be the answer in shillings. EXAMPLES. 1. What will be the value of 56 yards of ripounds of raisins, at 8 pence a band come to, at 7 pence a pound? 2. What will 48 yard? 3. What is the value of 541 yards of cotton shirting, at 94d. a ter yard? £1 10s. 3 d. Ans. 4. What will 672 pounds of butcome to at 112 pence a pound? Ans. £20 17s. old.. Ans. £32 18s. 251.

To find the value of any quantity consisting of several denominations, when the price of one hundred weight, &c. is given in several denom inations. RULE.-Multiply the price of a cwt. &c. by the number of hundreds. Divide the remainder of the quantity into aliquot parts, either of a cwt or of one another; then divide by the several aliquot parts, and the sum of the product and quotients will be the 252. How will you get the value of a quantity of several denominations, when the price of one cut. &c is given in different denominations? |
