Division of divers denominations.

RULE. In dividing into the left hand, or greater division of the given sum to be divided, divide as in whole numbers, and reduce the remainder, (if any,) to the next lowest denomination, adding to it the number of the same denomination in the given sum, and divide this in like manner; and so proceed till all are divided. If any remain after the last division is obtained, that remainder is of the same name as the dividend or denomination that was last divided.

EXAMPLES.

Here I give one to shew more clearly you are to proceed with the following. First, I say, how often is 4 contained in 5, which is 1, and 1 over. The t that is over is 1 ounce, which you must reduce to the next lowest denomination, which is pennyweights. By having the table of Troy weight committed to memory, ere you come this far, you will find 1 ounce contains 20 pennyweights, to which you add the 18 dwts. in the given sum, making 38; and divided by 4, the quotient is 9, which I set down in the place of pennyweights, and there is 2 over, which 2 is penny. weights. By the table, each pennyweight contains 24 grs. making 48 grains in the 2 dwts. and the 12 grs. in the given sum, will make 60 grains. Then I seek how often 4 will go into 6, (the first figure of the grains,) and find the quotient is 1, which I set in grains, and 2 over, which 2, with the cipher annexed to 6, make 20. Then I say, how often will 4 go into 20, and find the quotient 5, which I set down on the right hand of the last 1, making the quotient in all, 1 oz. 9 dwt. 15 grs.

Teaches to bring or change numbers of a higher denomination to that of a lower, yet retaining the same value.

RULE. Multiply the highest denomination given, by so many of the next less, as make one of that greater; and this continue, till you have brought it down as low as your question requires. But if there be smaller denominations attached to the greater, as 3 cwt. 2 qrs. 14 lbs. you must, in your multiplying, add in the denomination that is of the same name of that which you are reducing the higher one to, and so on, as for example:

Reduction ascending, (improperly called,) is the bringing a lower denomination to a greater, yet retaining the same value.

RULE. Divide the lowest denomination given, by as many of the same name as make one of the next greater or higher, and so on through all the denominations, as far as your question requires. But if there happens to be a remainder, after your first divisor is divided, that remainder is of the same name as the dividend, before it was divided; and all the remainders, throughout the operation of the

question, will be of the same name as the dividend, before it was divided. For example, bring 406 lbs. to cut. qrs. lbs. Here, 28 lbs. make a quarter, which I divide, because a quarter is the next highest denomination, and the quotient is 14, and 14 remains, which 14 is pounds, as the dividend was pounds, before it was divided by 28. Now, the quotient 14 is quarters, therefore the remainder, after that is divided, will be quarters. Here again I divide by 4, the next greatest denomination, as 4 qrs. make 1 cwt. and there remains 2, which 2 is quarters, and the quotient 3 cwt, See the operation.
