COMPOUND MULTIPLICATION consists in multiplying numbers of different denominations by simple numbers. £. 7 8. d. 127 the product to be 42d. 6 45 15 6 1. What will 6 bales of cloth cost, at 7£. 12s. 7d. per bale ? In this question, we multiply 7d. by 6, and find This we divide by 12, the number of pence in a shilling, and find it contains 3s. and 6d. We write the 6d. under the pence, and carry 3 to the product of 6 times 12, and find the amount to be 75s., which we reduce to pounds by dividing them by 20, and find them to be 3£. 15s. We write down the shillings under the shillings, and carry 3 to the product of 6 times 7£.; and we thus find the answer to be 45. 15s. 6d. From the above illustration we deduce the following RULE. When the multiplier is less than 12, multiply by the multiplier and carry as in Compound Addition. NOTE. For the answers in Multiplication, sce Section XV., in Division. 2.
