CHAP. CCCXCVII. Of the Exchanges of Placentia with Francfort.
* 1.1PLacentia doth Exchange with Francfort, and giveth Crowns 100 of Mark to have here Crow. 110½ of 93 Quarentines per Crown: I demand then for 800 Crowns of Mark, how many Flo∣rins of 60 Quarentines per Flor. shall I have in Francfort? Multiply the said Crow. 800 by Crow. 110½ per cent. cutting off the two last figures, the which multiply by 20 and by 12, to make them Sols and Deniers of Gold, and it comes to 884 Crowns of Quarentines 93, the which to make Florins, must be multiplied by 93 Quarentines, and they are 82212 Quarentines, from which cut off the last figure, and take ⅙ of the rest, and they then do make Florins 1370, and the tenth remaining, with the 2 Quarentines, which is the figure cut off, and it maketh 12, from which taking ⅓ to make them Sols, by reason that 3 Quarentines make one Sol, and they are Florins 1370, and Sols 4, which is the credit that must be rendred in Francfort, as shall appear by Example: 〈 math 〉〈 math 〉
