| Multiply 12 s. by 12 the product is | 156 |
| And 13 li. by 240 (because 240 pence make one pound) the product is | 3120 |
| To which adde the 4 d. | 4 |
| It makes in all | 3280 |
Then the question will be, If 20 sheep cost 3280 pence, what shall one sheep cost?

By the rule before delivered, I should multi∣ply the second number by the third, but in this example, the third number being 1, it doth not multiply; I therefore divide 3280 the second number, by 20 the first number, and the moti∣ent 164, is the price of one sheep in pence, which divided by 12, the quotient is 13 s. and 8 d. re∣maining, the price of every sheep therefore is 13 s. 8 d.
