Note. 5 cwt. 3 qrs. is 5cwt., that is 5.75 cwt. 2. At $25 per cwt., what cost 37 cwt. 3 qrs. 14 lb. of tobacco ? Note. The quarters and pounds may first be reduced to a common fraction and then to decinials. qrs. 14 lb. are 98 lb., that is of 1 cwt., and =.875; therefore, 37 cwt. 3 qrs. 14 lb. is equal to 37.875 cwt. ; this multiplied by 25 gives $946.875. 3. What cost 5 cwt. 2 qrs. 19 lb. of raisins, at $11 per cwt. ? 4. What cost 13 cwt. 1 qr. 15 lb. of iron, at $4.27 per cwt. ? per hhd. ? Note. 13 cwt. 1 qr. 15 lb.=1313 cwt.=13.383+cwt. This multiplied by $4.27 gives $57.14541. Observe, that there must be as many decimal places in the product as in the multiplicand and multiplier together. In this instance here are five places. It is not necessary to notice any thing smaller than mills in the result, therefore $57.145 will be sufficiently exact for the answer. 5. What cost 12 cwt.

What cost 2 grs. 3 nls. of broadcloth, at $6.42 per Express the fractions in the following examples in decimals. 19. What part of 1 yd. is 3 qrs. 2 nls. ? yard ? 24. What part of a day is 6 hours ? 37. At 2.£. 58. per cwt., what cost 5 cwt. 3 qrs. of raisins? Note. · 2£. 58.2.25£., and 5 cwt. 3 qrs.=5.75 cwt. Multiplying these together, the result is 12.9375€. The decimal part of this result may be changed to shillings and pence again. .9375£. is .9375 of 20 shillings; therefore if we multiply 20 shillings by .9375, or, which is the same thing, if we multiply .9375 by 20, we shall obtain the answer in shillings and parts of a shilling. This is evident also from another course of reasoning. .9375£. is now in pounds; if it be multiplied by 20 it will be reduced to shillings. .9375 20 18.7500 The result is 18 shillings and .75 of a shilling, which may in like manner be reduced to pence by multiplying it by 12. .75 9.00 The result is 9d. The answer, therefore, is 12£. 188. 9d. 38. What cost 3 cwt. 2 qrs. 7 lb. of hops, at 2£. 3s. 68. per cwt. ? 39. What cost 17 yds. 2 qrs. 2 nls. of broadcloth, at 2£. 5s. 7d. per yard ? 40.

How many cwt. of raisins in 7 casks, each cask con taining 2 cwt. O qrs. 25 lbs ? Note. 7=7.6 and 2 cwt. 0. qrs. 25 lb.=2.2232+ cwt. These multiplied together produce 16.8957 cwt. The fractional part of this may be changed to quarters, pounds, &c. as the fractions in the last examples were changed to shillings and pence. . .8957 cwt. is .8957 of 4 quarters, or it is hundred-weights and may be reduced to quarters and pounds by multiplying by 4, and by 28. .8957 5.0944 The answer is 16 cwt. 3 qrs. 16 lb. 51 oz. nearly. The same result may be obtained by changing the decimal .8957 cwt. to a common fraction, and proceeding according to the method given in Art. XVI. 43. How many cwt. of cotton in 57 bales, each bale containing 4 cwt. 3 qrs. 7 lb.? 44. How many cwt. of coffee in 13 bags, each bag con taining 1 cwt. 3 qrs. 15 lb. ? 45.
