Chamberlain's Arithmetick being a plain and easie explanation of the most useful and necessary art of arithmetick in whole numbers and fractions, that the meanest capacity may obtain the knowledge thereof in a very short time : whereunto are added many rules and tables of interest, rebate, purchases, gaging of cask, and extraction of the square and cube roots / composed by Robert Chamberlain, accomptant and practitioner in the mathematicks.

Example.

It is required to know or find out the true value of 283/487 of a Pound Sterling, the Fraction being given in a pound, the next inferior Denomination is shillings wherein 20 Units make an integer in pounds, there∣fore I multiply the Numerator of the given Fraction 283 by 20, the Product is 5660, which divide by 487 the Denominator, and the Quotient gives me 11 shilling, but there doth remain of this Division 303, which I multiply by 12 the number of Units in the next inferior Denomination, and the Product is 3636, which I likewise divide by 487, and the Quotient gives me 7 pence, and there doth remain 227, which I mul∣tiply by 4 the number of Units in the next inferior Denomination, and the Product 1008 I divide by 487 as before, and the Quotient gives me 2 farthings, and there still remains 34, which I put as a Nume∣rator over the old Denominator 487, so I find the just value of 283/487 of a pound ster∣ling is 11 s. 7 d. 2 f. 34/487 as you may see by the succeeding work.
