CHAP. CCCCXII. Of the Exchanges of Millan with Placentia.

* 1.1MIllan doth exchange with Placentia, and giveth posito Sols 133⅓, to have in Placentia one Crown of Mark; I demand then for Livers 9671. 16. 8. of Millan, how many Crowns of Mark must I have in Placentia?

First, reduce into Deniers the said 133⅓ Sols, multiplying them by 12, and adding 4 De∣niers for the ⅓ of a Sol. and they make Deniers 1600, and then to reduce into Deniers the said sum of Lire, multiply them by 20 and by 12, adding to the multiplication Sol. 16. and De∣niers 8, which account with the Livers, and they make Deniers 2321240, the which must be divided by Deniers 1600, the price of the Crown of Mark, and by division they will come to be Crowns, multiplying the rest of the division by 20 and then by 12, to make them Sols and Deniers of Gold, and they make Crow. 1450. 15. 6. of Mark, and so much will the said sum be in Placentia.
