TO REDUCE CANADA CURRENCY.
TO REDUCE NEW ENGLAND CURRENCY.
TO REDUCE NEW YORK CURRENCY. As 1 dollar is ,4 of a pound in this currency, there will be as many dollars in a sum of New York currency, as there are , 4 in it. Therefore

REDUCTION FROM ONE CURRENCY TO AN,
OTHER. The following table will enable the pupil to reduce a sum from one currency to another, with more facility than by any other method. Each fractional figure shows the relative value of a sum in one currency to the same sum in another currency.
For example, the in the second perpendicular and the fourth horizontal column, shows that £1 sterling is of the number which expresses the same value in New England currency Thus £6 sterling is $ of the number which expresses the same value in New England currency. That is, £6 is å of the answer to be obtained when the same value is expressed in New England currency. To find the answer, we reason thus. If £6 is three fourths, £2 is one fourth, and £8 is the answer : thus dividing by . RULE FOR CHANGING A SUM IN ONE CURRENCY, TO THE
