To divide by 10, 100, 1000, &c. RULE. Cut off as many figures from the right hand of the dividend as there are ciphers in the divisor, and the figures cut off are the remainder, and the other figures of the dividend are the quotient. 1.

The changing of numbers from one name to another, without altering their value, is called Reduction. EXAMPLES. 1. Reduce 148 dollars to cents and mills. Thus, 14800 cents. To reduce dollars to cents, mul = 148000 mills. tiply by 100, because 1 dollar 100 cents. That is, we annex 2 ciphers, and the whole will be cents. (See Rule for multiplying by 10, 100, &c. page 37.) And to reduce cents to mills, we annex 1 cipher, and the whole will be mills therefore to change dollars to mills, we annex 3 ciphers. 2. In 1386 dollars 8 cents, how many cents? Therefore, if the sum Thus, 138608 cents. Ans. consists of dollars and cents, join them together as a whole number, and the whole will be cents. (In this example, the cents being less than 10, we write a cipher before them, or in the tens' place, which must always be done in like cases.) And, if the sum consists of dollars, cents and mills, join them together in like manner, and they will express so many mills. Thus, 25 dollars, 41 cents, 5 mills 25415 mills. 3. In 138608 cents, how many dollars and cents? Thus, $1386, 08 = 1386 dols. 08 cents. Ans. To reduce cents to dollars, we divide by 100, because 100 cents 1 dol lar. (See Rule for dividing by 10, 100, &c. page 48.) That is, we cut off 2 figures to the right hand, and those on the left hand will be dollars; and to reduce mills to dollars, we point off three figures to the right; and those on the left will be dollars, and those on the right will be cents and mills. = Thus, 25415 mills $25,41,5, or 25 dols. 41 cts. 5 m. 4. Reduce 125 dollars to cents. 5. Reduce 12550 cents to dollars. Ans. 12500 cents. Ans. 6. Reduce 568 dollars, 9 cents, to cents. Ans. 56809 cents. 7. Reduce 56809 cents to dollars. Ans. 8.

Ans. $3,598. $954,10. 13. Reduce $96 12 cents to mills. 96125 mills. 14. In 96125 mills, how many dollars and cents? Ans. 96 dols. 12 cts. 15. Write down 125 dols. and 9 mills as a whole number. Ans. 125009 mills. MULTIPLICATION OF FEDERAL MONEY. RULE.

A merchant bought 18 bales of cloth, each bale containing 25 pieces, and each piece 31 yards, at,45 cts. a -yard; what did the whole come to ? Ans. $6277,50. DIVISION OF FEDERAL MONEY. RULE. Write down the given sum, and divide as in whole numbers; the quotient will be the answer in the lowest name in the given dividend. EXAMPLES. 1. If 3 yards of cloth cost 12 dols. 75 cts., what is that a yard? Operation. 3)1275 cts. Ans. 425 4 dols. 25 cts. $12,75 is 1275 cts., which we divide by 3, as a whole number, and the quotient is 425 cents, which reduced to dollars, is 4 dollars 25 cents, the Answer. 2. Divide 21 dollars 6 cents equally among 12 men. Operation. 12)2106,0 cts. mills Ans. 1755 mills.=1,75,5 21 dols. 6 cts. is 2106 cents, which we divide by 12, and there is a remainder, which, by annexing a cipher, makes 60 mills, in which 12 is contained 5 times, and the quotient is 1755 mills; which being reduced to dollars, is 1 dollar 75 cents 5 mills. 3. Divide 230 dollars equally among 16 men. $ 16)230(14,375 16 70 64 600 48 120 112 80 80 0 We divide $230 by 16, and the quotient is $14, and a remainder of $6, which we reduce to cents by annexing 2 ciphers. We divide again, and the quotient is 37 cts. and the remainder 8 cents. We then reduce 8 cents to mills by annexing 1 cipher, and dividing again gives 5 mills. Thus the answer is 14 dollars 37 cents 5 mills. But we may if we please, reduce $230 to mills 230000 mills; then divide by 16, and the quotient will be 14375 mills; which reduced to dollars is 14 dollars 37 cents 5 mills; the Answer: |
