Example.

It is required to multiply 36 5/9 by 18 ⅖, by the 1st of the 11, the mixt number 36 5/9 is 329/9 and the mixt number 18 ⅖ is 92/5, now multiply the two Numerators 329 and 92 together, the Product is 30268, which is your new Numerator, and the Product of the two Denominators 9 and 5 is 45 the new Denominator, so have you the improper Fraction 30268/45 being the

Product required; but if you divide the Numerator 30268 by the Denominator 45, the Quotient gives the whole number 672, and the remainer 28 is Numerator to the Divisor 45, so the mixt number 672 28/45 is the Product of 36 5/9 multiplied by 18 ⅖ as was required.

If a Compound Fraction be given to be multiplied by a Simple or Single Fraction, reduce that Compound Fraction given into a Simple one by the 6. of the 11th, and pro∣ceed according to the instructions of the first Example, in multiplying one by another.
