Fractions is performed by drawing of a line, and placing an unite underneath it, in form of a fraction, as if the dayes in a vul∣gar year were to be made an im∣proper fraction, it will be 365/1 as in the margent; if an Integer and a Fraction were to be reduced into one Fraction, equall to the mixt number propoun∣ded, multiply the Integer by the Denominator of the Fraction given, and to the Product adde the Numerator, the summe will be the Numerator of a mixt improper Fraction, whose Denominator was the former Multiplier: there are 52 weeks, and 1 day in a vulgar yeare, which mixt number is to be

reduced into a Fraction, set downe the number given 52 1/7 as in the margent, then multiply 52 by 7 (the Denominator of the fraction) the quotient will be 364, unto which adde 1 the Numerator, the summe is 365; under which draw a line and sub∣scribe the Denominator 7, there will be 365/7 a mixt improper faction, equall unto 52 1/7 as in the Table does appear, or reduced by the last Paradigma in dividing the Numerator by the Denominator.
