When a sum or quantity is to be changed to a higher denomination than its own, work by RULE 2.* Divide the given sum or quantity by that number of its own denomination which makes one of the denomination to which it is to be changed. See notes 1, 2, and 3. When there are one or more denominations between the denomination of the given sum or quantity and that to which it is to be changed; first change it to the one next higher than its own, and then to the next higher, and so on.-See notes 4 and 5. 7 Remainders are of the same denomination as the sum or quantity divided.–See examples 2, 6, 8, 10, and 12, in English money. * The reason of this rule may be seen by considering that as it takes twenty shillings to make one pound, there must be just as many pounds in any number of shillings as there are twenties in that number; and that to find how many twenties there are in any num. ber, we divide it by 20. |
