The vvell spryng of sciences whiche teacheth the perfecte woorke and practise of arithmeticke, bothe in whole nombers and fractions, with suche easie and compendious instruction into the said arte, as hath not heretofore been by any sette out nor laboured. Beautified with moste necessary rules and questions, not onely profitable for marchauntes, but also for all artificers, as in the table doeth partlie appere: set forthe by Humfrey Baker citezeine of Lo[n]don.

¶ Example.

If. 15. shillynges worthe of Wine wil serue for the ordinary of. 46 men when the Tonne of Wine is worthe 12. poundes: for howe many menne will the same. 15. shillynges suffice, when the Tonne of Wine is worthe but. 8. poundes? It is certain, that the lower the price is, that the Tonne of Wine doeth coste, and so many more persones will the saied. 15. shillynges in Wine suffice. Therefore set doune your nombers thus, if. 12. poundes suffice. 46. menne, how many will. 8. poundes suffice, you muste multiplie 46. by. 12. and thereof commeth. 552. the whiche. 552. you shall diuide by. 8. and thereof commeth. 69. and vnto 69. menne will the saied. 15. shillyn∣ges worthe in Wine suffice, when the Tonne of Wine is worthe but eight poundes, as hereafter dooeth appeare by practise.

Likewise, a messenger maketh a iourney in. 24. daies, when the daie is but, 12. houres long: how many daies shal he be vpon the same iourney, whē the daie is. 16 houres in length? Here you must perceiue, that the more hou∣res are in a daie, the fewer daies will the messenger bee in goyng his iour∣uey. Therefore write doune your nō∣bers thus, as here you maie se. 〈 math 〉〈 math 〉

And then multiplie 24. daies by. 12

houres, and thereof commeth. 288. di∣uide the same. 288. by the thirde nom∣ber. 16. and you shall finde 18. the whi∣che is. 18. daies, and in so many daies will the messenger make his iourney when the daie is. 16. houres long.

Likewise, when the Bushell of wheate doeth coste. 3. shillynges, the penie loafe of bread waieth. 4. lib.

I demaunde what the same penie loafe shall weye, when the bushell of wheate is worthe but twoo shillyn∣ges: here is to bee considered, that the better cheape the Wheate is, the hea∣uier shall the pennie loafe wiie, and therefore write doune your. 3. nom∣bers, thus. 〈 math 〉〈 math 〉

Then multiplie. 4. lib. whiche is the secōde nomber, by the first nomber 3. and thei make. 12. the which. 12 you

shall diuide by the thirde nōber. 2. and thereof commeth. 6. lib. and so muche muste the penie loafe of breade waye, when the bushell of wheate is worthe but twoo shillynges, as maie appere.

And nowe, accordyng to my for∣mer promise, shall followe the seconde parte of Arithmeticke, whiche teacheth the workyng by Fractions.
