NOTE. To find the true remainder, we multiply the last remainder by the last divisor but one, and, to the product, add the next preceding remainder; we multiply this sum by the next preceding divisor, and to the product add the next preceding remainder; and so on, till we have gone through all the divisors and remainders to the first. This rule will be better understood by the pupil, after he has become acquainted with fractions. 1. Divide 47932 by 72. 9)47932 EXAMPLES. As 72 is equal to 9 times 8, we first divide the dividend by 9, and the quotient, thence arising by 8; and to find the true remainder, we multiply the last remainder, 5, by the first 665-552 divisor, 9; and to the product add the first remainder, 7; and find the amount to be 52. 2. Divide 5371 by 192. 4)5871 6)1342-3 8)223 4 We find 192 equal to the product of 4 times 6 times 8.: = 4 X 6 X 8=192. We therefore divide by these factors, as in the last example. To find the true remainder, we multiply the last remainder, 7, by the last 27 7187 divisor but one, 6; and to the product add the last remainder but one, 4; this sum we multiply by the first divisor, 4; and to the product add the first remainder, 3; and find the amount to be 187. 1 What number multiplied by 1728 will produce 1705536 ? 2.

NOTE."The original of all weights, used in England, was a grain or corn of wheat, gathered out of the middle of the ear; and, being well dried, 32 of them were to make one pennyweight, 20 pennyweights one ounce, and 12 ounces one pound. But in later times, it was thought sufficient to divide the same pennyweight into 24 equal parts, still called grains, being the least weight now in common use; and from hence the rest are computed." Apothecaries mix their medicines by this weight; but buy and sell by Avoirdupois. The pound and ounce of this weight are the same as in Troy Weight. = 80 = 20 = 1 By this weight are weighed almost every kind of goods, and all metals except gold and silver. By a late law of Massachusetts, the cwt. contains 100 lbs. instead of 112 lbs. |
