77 De carica Provincie¹⁶³

Carica Provincie¹⁶⁴, que pensat¹⁶⁵ libras 300, venditur pro libris 15 et soldis 7, hoc

⑥ 307 £ l. \({7 \over 20}\) 15 300   ② pensa per 7 est ⑤   \({2~~0~~\phantom{1}0~~\phantom{1}8 \over 5~~5~~12~~20}\) 4 86

¹⁶⁶ est pro libris \({7 \over 20}\) 15; queritur quantum valent libre 86. Multiplica 15 per 20 et adde 7; erunt 307, que pone super 15 et multiplica ea¹⁶⁷ per 86; erunt 26402, que divide per 300 et per 20, hoc est per \({1~~0~~\phantom{1}0~~\phantom{1}0 \over 5~~5~~12~~20}\): exibunt libre \({2~~0~~\phantom{1}0~~\phantom{1}8 \over 5~~5~~12~~20}\) 4 pro pretio quesitarum librarum 86, ut hic ostenditur.

78 Sic enim debes studere invenire regulas numerorum quibus divisio¹⁶⁸ pervenit sicuti modo fecimus de 300: quamvis ipsius regula sit \({1~~\phantom{1}0~~\phantom{1}0 \over 3~~10~~10}\), tamen eam esse \({1~~0~~\phantom{1}0 \over 5~~5~~12}\) posuimus, ut habeamus¹⁶⁹ [S:44r] \({1 \over 12}\) sicuti habemus \({1 \over 20}\), illam¹⁷⁰ scilicet¹⁷¹ que est¹⁷² cum 15.

79 De eadem carica¹⁷³

Item carica piperis valet libras 11 et soldos 7 et denarios 5, hoc

⑫ 2729 £ l. \({\phantom{1}5~~\phantom{1}7 \over 12~~20}\) 11 300 ⑥ ⑦ pensa per 13 91787 \({1~~6~~6~~\phantom{1}0~~\phantom{1}6~~\phantom{1}6~~\phantom{1}7~~16 \over 3~~8~~9~~10~~10~~10~~12~~20}\) 4 \({1~~1~~1~~\phantom{1}5 \over 5~~4~~3~~12}\) 127

¹⁷⁴ est libras \({\phantom{1}5~~\phantom{1}7 \over 12~~20}\) 11; quantum valent ergo libre 127 et uncie \({1 \over 5}\) \({1 \over 4}\) \({1 \over 3}\) 5, hoc est \({1~~1~~1~~\phantom{1}5 \over 5~~4~~3~~12}\) 127? Describe questionem, et multiplica 11 per suam virgulam: erunt 2729, que pone super 11. Item multiplica 127 per suas virgulas, hoc est per 12 et adde¹⁷⁵ 5, que per 3 et adde¹⁷⁶ 1, que per 4, que per¹⁷⁷ 5: erunt 91760. Item multiplica 1 quod est super 4 per 5, que per 3: erunt 15. 80 Rursus multiplica 1 quod est super 5 per 4, que per 3: erunt 12, que adde cum 15 et cum 91760; erunt 91787, que pone super 127, et multiplica ea per 2729: erunt 250486723¹⁷⁸, que divide per regulam de 300 et per omnes ruptos: exibunt libre \({1~~6~~6~~\phantom{1}0~~\phantom{1}6~~\phantom{1}6~~\phantom{1}7~~16 \over 3~~8~~9~~10~~10~~10~~12~~20}\)¹⁷⁹ 4 pro pretio illarum quesitarum librarum.
