SECTION 8.

REDUCTION OF COMPOUND NUMBERS. Reduction is the operation of changing any quantity from its number in one denomination, to its number in another denomination. For instance, if we change an admeasurement from 2 feet to 24 inches, that is, if we find how many inches there are in 2 feet, the operation is called reduction. Again, if we change 24 inches. to 2 feet, this operation is also called reduction.

In this example, we conThis example is the resider, that there are 20 verse of the first example. times as many shillings as We here consider, that ev pounds in any sum; there- ery 4 farthings make 1 penfore we multiply the 13 ny; therefore, we find by pounds by 20, and add the 8 shillings to the product. Then, since there are 12 times as many pence as there are shillings, we multiply the shillings by 12 and add the 4 pence to the product. Lastly, since there are 4 times as many farthings as pence, we multiply the pence by 4, and add 2 farthings to the product.

division how many times 4 there are in the number of farthings: the quotient is pence, and the remainder is farthings. Then, since ev ery 12 pence is 1 shilling, we divide the pence by 12. the quotient is shillings, and the remainder pence Lastly, since every 20 shil lings make 1 pound, we d vide the shillings by 20.

RULE FOR REDUCTION. When a greater denomination is to be reduced to a smaller, multiply the greater denomination, by that number which is required of the smaller, to make ONE of the greater; adding to the product so many of the smaller denomination as are expressed in the given sum. Perform a like operation on this product, and on each succeeding product.

When a smaller denomination is to be reduced to a greater, divide the smaller denomination by that number which is required of the smaller, to make ONE of the next greater: the quotient will be of the greater denomination, and the remainder will be of the same denomination with the dividend. Perform a like operation on this quotient, and on each succeeding quotient.
