CHAP. CCCXXXXI. Of the Exchanges of Rome with Millan.
* 1.1ROme exchangeth with Millan, and giveth posito Crown. 87⅘ of Estampe, to have in that place Crowns 100 of Livers 5. Sol. 17 per Crown; I demand, for Crowns 2140. 16 of Estampe, how many Livers of Millan shall I have?
First, reduce the price and the Crowns into
Sols of Gold, multiplying them by 20, and to the multiplication add 16
Sol. ⅘ of a Crown, and then say by the Rule of Three, If the Sols coming of the price, give Crowns 100, how many will the Sols coming of the abovesaid sum of
Crowns give? and multiplying the remainder of the Division by 20 and by 12, to make them Sols and Deniers of Gold, they will make
Crowns 2438. 5. 4 d. the which you must reduce into
Livers, by multiplying them by l. 5. 17. and they will make
l. 14263. 17. 2 d. which I must have at Millan for the said sum of Crowns of Estampe; as appeareth plainly by this Example. 〈 math 〉〈 math 〉
* 1.2The proof of this Rule is apparent, when Millan shall exchange with
Rome.
