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.

¶ Reduction of whole nombers and broken together into a Fraction.

IF you will reduce whole nō∣ber * 1.1 with broken, you muste bryng the whole nomber in∣to brokē, as by this example maie appere: reduce 17. ⅝ into a brokē nomber, firste you must multiple the whole nomber. 17. by the denomina∣tor of the broken, whiche is. 8. in sai∣yng. 8. tymes. 17. doe masse. 136. vnto the whiche you muste adde the nume∣rator of. ⅚ whiche is. 5. and al amoun∣teth to. 141. whiche sette ouer. 8. with a line betwene theim, and thei will bee 141/8 so muche is. 17. ⅝. worthe in a frac∣tion, as it appeareth here by practise. 〈 math 〉〈 math 〉

In case you haue whole number and broken to bee reduced, with broken you muste bringe the whole number into his broken, in multiplyinge it by the denominator of the broken num∣ber going therwith, and adde there∣unto the numerator of the saide bro¦ken number, as in the laste example, and then reduce that broken number wyth the other broken, as here appe∣reth by this example. Reduce 10. ⅔ & 4/7 togither, first bring 10⅔ al into thirds, as by the syxt reduction, and you shal finde 〈◊〉〈◊〉, then reduce the 32/3 and 4/7 togi∣ther, by the fyrste reduction, and you shall finde 224/21 for the 32/3: and 〈◊〉〈◊〉 for 〈◊〉〈◊〉 as appereth here by practise. 〈 math 〉〈 math 〉

Also in case you haue in bothe partes of your Reduction, as well whole nū∣ber as broken, you must alwayes put the whole into their broken (as by the syxte reduction) of either part.
