Divide these crowns, sols and deniers by the parts which 1 crown is of 11. Sterling, and the quotient or sum of the quotients will be the sterling money required. 69.

The foregoing method is universal; but may be contracted in some cases, viz. When the rate of exchange is 30d. or 2s. 6d. p" crown, 2s. 6d. is H. consequently in this case every pound sterling contains 8 crowns, wherefore the English money multiplied by 8, will produce the crowns required. Note. If the English money be pounds, shillings and pence, the answer will result crowns, sols and deniers d'or, which being multiplied by 3 throughout, will give the answer in livres, sols and deniers tournois. And if the rate exceed 30d. by an even part thereof, as 324d. exceeds it by 24, 1% of 30, then 2+ is contained just once more in the given rate 32; than in the assumed rate 30, viz. 13 times; and 32; is # of itself and 30;3 of the same. Therefore 32; : 30 | :) :: #3 or i : #3, or 1—os: so that if I's be deducted, the remainder will manifestly be in the ratio to the crowns required as # thereof. And the same is shewn of any other rate which exceeds 30d. or ?s. 6d. by an aliquot part thereof, according to the following Rule - Rule. If the rates exceed 30d. by an even part of itself, deduet that part of the sterling money from itself, which is denominated by one more than the excess is of 30d. and multiply the remainder by 8. Accordingly let such of the foregoing as fall under this, Rule be done.
