PROBLEM: Resulting from a comparison of the compound rules, by the operation of which many questions may be solved in a short and elegant manner. 1. Having the sum of two numbers, and one of them given to find the other. Rule.-Subtract the given number from the given sum, and the remainder will be the number required. Let 154 be the sum of two numbers, one of which is 84, the other is required. 154 sum-84 given number=70 the other. 2. Having the greater of two numbers, and the difference between that and the less given, to find the less. RULE. Subtract one from the other. If the greater number be 672, and the difference between that and the less 389, required the other number. 672 given389 difference=283 less. 3. Having the least of two numbers given, and the difference between that and the greater, to find the greater. Rule.- Add them together. The less number is 142, and the difference 167; required he greater number. 309 greater number. re 4. Having the product of two numbers, and one of them given, to find the other. Rule. Divide the product by the given number, and the quo. tient will be the number required. If the product of two numbers be 196, and one of them 4, quired the other. Thus : 196-4=49. Ans. 5. Having the dividend and quotient, to find the divisor. Rule. Divide the dividend by the quotient. This will prove division. Let the dividend be 144, and the quotient 16, required the divisor ? 144:16=9. Ans. 6. Having the divisor and quotient given, to find the dividend. RULE. Multiply them together. Let the divisor be 6, and the quotient 72, required the dividend. 72 X6=432. Ans. EXAMPLES. 1. Suppose a man born in the year 1743, when will he be 77 years of age ? Ans. 1820. 2. What number is that, which if it be added to 19418 will make 21802 ? Ans. 2384. 3. What number must you multiply by 9, that the product may be 675 ? Ans. 75. 4. What is the difference between thrice five and thirty, and thrice thirty-five ? Ans. 60. 5. If a man spend 192D. in a year, how much is that per cal. endar month? 6. A. borrowed at different times the following sums, namely: of B. D625 ; of C. D721.50 ; of D. D842; and he is indebted to others as much as he has borrowed, abating D125.50 ; he is now prepared to retire from business ; required the amount of his debts. Ans. D4251.50 7. General Burgoyne and his army were captured at Saratoga, N. Y., by General Gates, October 17, 1777, and Earl Cornwallis and his army surrendered to General Washington at York, Va., October 19, 1781 ; required the space of time between. Ans. 4 years, 2 days 8.

REDUCTION OF DECIMALS. The two following cases of Reduction of Decimals are the very reverse of each other, and by reversing the rule, one will prove the other. The use of the rule is to change a denomination, or several denominations, from their given expression into a decimal quantity having the same value, for the purposes of multiplication, division, &c., which will then become the same as whole numbers. Thus, if you wish to find the decimal expression of 2 quarters, 14 pounds, avoirdupois, first reduce it to pounds, 2 x 28=56+14=70 pounds; now annex ciphers to the 70 pounds, and divide by 112 lbs.=1 cwt, of which you wish to make it a decimal, and you have .625; 9266==; for 14)11 3. Again, you wish to reverse the rule, and give the .625 the expression in the terms of the integer, or to reduce it to its proper value. Thus .625 cwt. multiply by the next less denomination, which is 4 qrs., and count off the three places for decimals, according to the rule in multiplication of decimals, and the quantity at the left of the decimal point is of the same name with the multiplier, that is, 2 qrs. ; then multiply the remaining decimal, .500, by the next less denomination, namely, 28 lbs., and count off as before, and you have 2 quarters, 14 pounds= 1000=112=cwt., &c. The correctness of the operation of the rule is evident from the nature of decimals, and the explanations already given in the preceding pages. In the third case : to reduce a vulgar fraction to its equivalent decimal, by annexing one, two, three, or more ciphers to the numerator, the value of the fraction is increased ten, a hundred, or more times. After dividing, the quotient will, of course, be ten, a hundred, or more times, too much ; the quotient must, therefore, be divided by ten, a hundred, &c., to give the true quotient or fraction. In the first example, is 1900="15, which divided by 1000 is 128=.125, and this is the rule. |
