PROBLEM H.

A short and easy method to find the value of any deci

mal of a pound by inspection.

RULE.

Double the first figure, or place of tenths for shillings, and if the second figure be 5, or more than 5, reckon another shilling ; then, after this 5 is deducted, call the figures in the second and third places so many farthings, abating 1 when they are above 12, and 2 when above 36, and the result will be the answer.

Note. When the decimal has but 2 figures, if any thing remains after the shillings are taken out, a cipher must be annexed to the left hand, or supposed to be so.

EXAMPLES.

1. Find the value of £. ,679 by inspection.

195.=double of 6
1 for the 5 in the second place which is to be

REDUCTION OF CURRENCIES.

RULES, For reducing the Currencies of the several United States* into Federal Money.

CASE I.

To reduce the currencies of the different states, where a dollar is an even number of shillings, to Federal Money.

They are
F-New-England, New York, and 2
Virginia,

North Carolina.'
Kentucký, and
Tennessee.

RULE. "1. When the sum consists of pounds only, annex a cipher to the pounds, and divide by half the number of shillings in a dollar ; the quotient will be dollars.t

2. But if the sum consists of pounds, shillings, pence, &c. bring the given sum into shillings, and reduce the pence and farthings to a decimal of a shilling; annex said decimal to the shillings, with a decimal point between, then divide the whole by the number of shillings contained in a dollar, and the quotient will be dollars, cents, mills, &c.

* Formerly the pound was of the same sterling value in all the colonies as in Great-Britain, and a Spanish Dollar worth 4s6-but the legislatures of the different colonies emited bills of credit, which afterwards deprecia. ted in their value, in some states rore, in others less, &c.

Thus a dollar is reckoned in New-England, New Jersey,

SouthVirginia, Pennsylvania, 68

786

Carolina, Kentucky, and

488 Delaware, and

and Tennessee. Maryland.

Georgia.
New-York, &
N. Carolina. S

+Adding a cipher to the pounds, multiplies the whole by 10, bringing them into tenths of a pound; then because a dollar is just three-tenths of a pound N. E. currency, dividing those tenths by 3, brings them into dollars, &c. See Note, page 85.
