Example.
It is required to multiply 7/9 of ⅗ of ⅚ by 6/7 of ¾ of 2/8 by the 6th of the 11th, the Com∣pound Fraction 7/9 of ⅗ of ⅚ is reduced unto 105/270 and 6/7 of ¾ of ⅔ unto 36/84, multiply these two simple Fractions Numerator by Nume∣rator, and Denominator by Denominator, and you will have the new Fraction 3750/22680, which by abbreviation is 125/756, both which last Fractions are either of them equal to the Product of the two given Compound Fractions, multiplied one by another as was required.
If it be required to multiply a Fraction by a whole number, make that whole num∣ber a Numerator, and set 1 under him for a Denominator, so the Fraction will be im∣proper, but multiply their Numerators and Denominators together as before.
