CASE

When different denominations are divided, by any number not exceeding 12.

RULE.

Divide the highest denomination first. The remainder, if any, must be brought to the next lower denomination; and, after adding it to the next lower denomination, divide the sum by your divisor and proceed thus, with all the denominations, till the work is finished.

CASE 2.

When the divisor is the product of two, or more numbers multiplied together, as they are found in the table.

RULE.

Divide, first, by one of those numbers, and the quotient by the other. The last quotient will be the answer.

REDUCTION.

By Reduction we change money, measures, weights, &c. our of one denomination into another, and yet retaining the same value. Of this there are two kinds, viz. Reduction Descending, and Reduction Ascending.

1. Reduction Descending is performed by multiplication. 2. Reduction Ascending is performed by division.

REDUCTION DESCENDING.

RULE.

Multiply the highest denomination, by the number of the next less which makes one of that highest; be careful to add to your product the figures of your next less denomination, and proceed in this manner till you have finished the work.

OF MONEY.

X 4 farthings in a penny.

83258farthings; the Answer.

In multiplying by 20, I added the 148. In X12, I added the 64. Inx4, I added 2gr. Which must always be done in similar

cases.

To prove questions in this rule, change the order of them. The foregoing question will become-In 83258 farthings, How many pounds?

REDUCTION ASCENDING.

By Reduction Ascending, less denominations are brought into higher.

RULE.

First, divide the sum by that number, which it takes to make one in the next higher denomination; secondly, divide the greatest, which it takes in that denomination, to make one in the next higher; and proceed in the same manner, through all the denominations, till the work be done.
