CASE I.

When the price of 1 yard, 1 H, &c. is an even part of one fbilling-Find the value of the given quantity at Is. per yard, h, &c. then draw a line underneath, and divide it by that even part, and the quotient will be the answer in fhillings; which must always be brought into pounds.

When the price is pence, and no even part of a shilling Find the value of the given quantity at Is. per yard ;. divide the pence into aliquot parts, for divifors; and the fun of the quotients, ariling from them, will be the anfwer.

When the price is pence or farthings, and an even part of a pound, cut off the right hand figure of the given quantity and the cypher, in the aliquot part (if it has one) and divide by the remaining figure or figures: When you come to the remainder, double it; and divide as before: The anfwer will be pounds, fhillings, &c. If there be no cypher in the divifor, then none fhould be cut off from the dividend.

When the price is any even number of billings under 40 ;—~ Multiply the given quantity, by half the price; and double the first figure of the product for fhillings; the reft of the product will be pounds.

. N. B. If the price be 2s. you need only double the unit figure for fhillings; the other figures will be pounds.

EXAMPLES.

I. What will 746 yards coft, at 2s. per yard? 745

Anf. £74 12 value at 2s. per yard.

Note. The above is done, by faying, twice 6 (the unit figure) is 12; the other figures, viz. 74, are pounds.

2. What will 5674 yards, at 2s. per yard, come to? Anj. £56 15/5.

N. B. Before I double the unit figure, viz. 7, I confider, that of a yard, at 28. per yard, will amount to 15; then, 1 double 7, which makes 148. and 1/6 added, makes 15/6; the other figures are pounds.
