TEACHES to find how often one number is contained in another of different denominations.

DIVISION OF FEDERAL MONEY.

Any sum in Federal Money may be divided as a whole number; for, if dollars and cents be written down as a simple number, the whole will be cents; and if the sum consists of dollars only, annex two cyphers to the doilars, and the whole will be cents; hence the following

GENERAL RULE.

Write down the given sum in cents, and divide as in whole numbers; the quotient will be the answer in cents.

NOTE. If the cents in the given sum are less than 10, you must always place a cypher on their left, or in the ten's place of the cents, before you write them down.
