The quantity is then said to be reduced to a higher name or denom ination. RULE XXXIV. $176. To reduce a Quantity to a HIGHER DENOMINATION. 1. Divide a monominal of a lower denomination, or the lowest term of a polynomial, by the number of that denomination which makes a unit of the next higher denomination: the quotient will be in the higher denomination. 2. This quotient may, in like manner, be reduced to a still higher denomination, and so on, observing that each higher term in a polynomial must be added to the quotient in the same denomination with itself. 3. In reducing a MONOMIAL INTEGER to higher denominations, each remainder may be reserved in the same denomination with the dividend whence it is derived, and the last quotient and the several remainders be afterwards arranged as the terms of a polynomial. EXAMPLE. To reduce 10 s. 6 d. 2 gr. to the denomination of £. We take the lowest term 2 gr. and divide it by 4, because 4 qr. make 1 d., a unit of the next higher denomination. We then add the 6d. to the d., and divide by 12, because 12 d. make 1 s., a unit of the next higher denomination. 6 12 s. 128. We next add the 10 s. to the 2 s. and divide by 20, because 20 s. make 1£, a unit of the next higher denomination. Thus we find 10 s. 6d. 2 gr. to be equal to £. The same reductions performed decimally, will be presented thus; 2 qr.÷4=.5 d.; 6.5 d.÷12=.541' s.; 10.541' s.÷÷20=.527' £. Another method of Reducing a Polynomial to a Fraction of a Higher Denomination. $177. A Polynomial may also be reduced to a vulgar fraction of a higher denomination, by reducing the given quantity to its lowest denomination, for a numerator, and reducing a unit of the higher denomination to the same lowest denomination, for a denominator. Thus to reduce 10 s. 6 d. 2 gr. to the fraction of a £. 10 s. 6 d. 2 qr.=506 qr.; and 1 £=960 qr. The fraction will then be 588 £=23 £. And this fraction reduced to a decimal (§ 153) gives .527' £, the same as in the preceding example. EXERCISES. 1. Reduce 8 oz. 15 dwt. 18 gr. to a fraction of a lb. Ans. 188 lb. 2.
