When the divisor is a composite number, that is, if any two figures, being multiplied together, will make that number, then divide the dividend by one of those figures, and the first quotient by the other figure, and it will then give the quotient required.-But as it sometimes happens that there is a remainder to each of the quotients, and neither of them the true one, it may be found by this RULE. Multiply the first divisor by the last remainder, and to the product add the first remainder, which will give the true one. When the price of a ton or 2240 lbs. of Old Sable iron is $112, how much is it per lb. ? (40)11200 Or, 2240)11200(5 cents. 11200 To divide by mixed numbers, or a whole number and a fraction. RULE. Reduce the divisor and dividend into the same name, and divide as usual; if there is a remainder, reduce it to its value in integers. EXAMPLES. In 3461 yards, how many perches of 51 yards each? How many perches or poles, of 16 feet each, in 1790 feet? When the divisor is 10, 100, 1000, &c. the figures of the dividend, that remain after pointing, give the quotient or answer without dividing, and in this way, mills and cents |
