.750000 we multiply by 4, and pointing off have 3 farthings, which, taken with the other denominations obtained, gives 15s. 9d. 3far. for the answer. RULE. Multiply the decimal by that number which will reduce it to the next lower denomination, and point off as in multiplication of decimals. Then, multiply the decimal part of the product, and point off as before. So continue till the decimal is reduced to the denominations required. The several whole numbers of the successive products will be the answer. NOTE. When there is a decimal in the last product, it may be changed to a common fraction. EXAMPLES. 2.

A CIRCULATING DECIMAL is a decimal in which one or more figures are continually repeated in the same order. Thus, in reducing to an equivalent decimal, on annexing ciphers and dividing by the denominator, the result obtained, .333, is a circulating decimal; for, however far the division might be carried, the same figure would continue to be repeated without the decimal terminating. Such decimals are sometimes called infinite, or repeating; and, for sake of distinguishing, those decimals that terminate are sometimes termed finite. 282. A repetend is a figure, or a series of figures, continually repeated. To mark a repetend, a point (.) is placed over a single repeating figure, or over the first and last of a series of repeating figures. Thus, in .3, the point denotes that the 3 is a repetend; and in .72, that the 72 is a repetend. 283. A single repetend is one in which only one figure is repeated; as in .1111+ denoted by .i; and 2222+, denoted by .2. 284. A compound repetend is one in which the same set of figures is repeated; as in .135135+, denoted by .i35, and .30363036+, denoted by 3036. 285. A pure repetend is one which contains only the figures of the repetend; as, .3, .02, and .123. 286. A mixed repetend is one in which a repetend is preceded in the same fraction by one or more figures. The figures preceding the repetend are called the finite part. Thus, .416 is a mixed repetend, of which the figure 6 is the repetend, and the figures 41 the finite part; also, 1.728 is a mixed repetend, of which the figures 28 are the repetend, and the figures 1.7 the finite part. 287. A perfect repetend is a pure repetend containing the same number of figures as there are units in its denominator less one. Thus, ✈ reduced to a decimal gives .142857, which, as it contains as many figures as there are units in the denominator, 7, less one, is a perfect repetend. 288. Similar repetends are those which begin at the same distance from the decimal point; as .3 and .6; or 5.123 and 3.478. 289. Dissimilar repetends are those which begin at different distances from the decimal point; as .986 and .4625; or .5925 and .0423436. 290. Conterminous repetends are those which terminate at the same distance from the decimal point; as .631 and .465, or .0753 and .4752. 291. Similar and conterminous repetends are those which both begin and end at the same distance from the decimal point; as .354 and .425; or .5757 and 5723. 292. Repetends always arise from common fractions, which, when in their lowest terms, contain in their denominator other factors than 2 and. 5. For when a common fraction is in its lowest terms, its numerator and denominator are prime to each |
