When the divisor does not exceed 12. RULE. Begin with the highest denomination, and divide as in Simple Division; and if there be a remainder, find how many of the next lower denomination it is equal to, which add to the next denomination; then divide again, and carry the remainder, if any, as before : thus proceed till the whole is finished. Proof—the same as Simple Division. EXAMPLES. £ s. d. qrs. 1. If £2047 13s. 9d. be divided equally among 6 men, how much will each man receive ? Illustration.--We divide the pounds Operation. as a whole number, by 6, and the 6)2047 13 9 0 remainder, 1 pound, is equal to 20s. which we add to the next denomina341 5 7 2 tion, 13s. makes 33s. which divided by 6, the quotient is 5s. and the remainder 3s. We then multiply the 3s. by 12, the number of pence in one shilling, and add in the 9d. makes 45d.; this divided by 6, the quotient is 7d., and the remainder 3d., which we multiply by 4, makes 12qrs.; which being divided by 6, the quotient is 2qrs. 2.

When the divisor exceeds 12, and is not a composite number, divide by the whole divisor at once, after the manner of Long Division. 17. Divide £176 9 shillings 6 pence, by 26. 26)176 9 616 ist. We divide the pounds, § 66 and the quotient is £6, and 156 the remainder £20. This 20 remainder we now multiply 20 by 20, the number of shil. lings in 1 pound, and to the 26)409(15 product add the 9 shillings 26 in the dividend, which makes 149 409 shillings; this sum we 130 divide by 26, as before, and the quotient is 15 shillings, 12 and the remainder is 19 shild. lings. We then multiply the 26)23419 19 shillings by 12, the num234 ber of pence in one shilling, and to the product add the 0 6 pence in the dividend, making 234 pence: this sum, divided by 26, as before, the quotient is 9d. We now have for the quotient £6 15s. 9d S. 19 18. If 31 yards of cloth cost £113 138. 4d. how much is that a yard ? Ans. £3 13s. 4d. 19. Divide 201cwt. 3qrs. 21lb. by 41.

When the divisor exceeds 12, and posite number, how do you proceed ? is not a composite number, how do you proceed? REDUCTION. Reduction teaches to bring numbers from one name, or denomination, to another, without altering their value. Reduction is of two kinds, Descending and Ascending. Descending is when higher denominations are brought into lower, as days into hours, &c., and is performed by multiplication. Ascending is when lower denominations are brought into higher, as hours into days, &c., and is performed by division. RULE. 1. To reduce high denominations to lower.--Multiply the highest denomination given by so many of the next less as make one of that greater, and to the product add the next lower denomination, (if any ;) thus proceed with each succeeding denomination, until you have brought it to the denomination required. II. To reduce low denominations to higher.—Divide the lowest denomination given by that number of the same denomination which it takes to make one of the next higher; thus proceed with each succeeding denomination, until you have brought it to the denomination required. Proof.-Reduction Ascending and Descending alternate ly prove each other. |
