Place the £ 35 12s. 6d. on your 19 slates as you see it on the Card, with 19 before 16 it for a divisor—Then seek how many 20 times 19 in 35—say l; set 1 off at the 19)332(17s. right hand for a quotient; this is i 19 pound, because you can have once 19 in 35. Now multiply 19 the divisor, by 1 and place the product under 35—subtract the remainder is 16—This is 16 pounds 12 to be multiplied by 20 to bring it into 1911406d. shillings, and the 12s. must be added in 114 the product, which will make 332s. Thus, 0 times 6 is 0, but 2 in the 12s. Ans. £1 17 6 makes 2; set 2 in the place of units. Then, twice 6 are 12, and 1 in the 12s. above makes 13; set 3 in the place of tens—carry 1. Then, twice 1 makes 2 and 1 I carried makes 3 ; set another 3 in the place of hundreds. Thus you have for a product, 332s. How many times 19 in 332? First seek how many times 19 in 33 ? say 1-place 1 off at the right for a quotientmultiply 19 by 1-place the product under 33–subtractthe remainder is 14. Bring down the 2 to the right side of 14, makes 142– seek how many times 19 in 142–7 times--place 7 on the right of 1 in the quotient. This makes 17s. Now multiply 19 by 7—place the product under 142subtract-the remainder is 9s. to be reduced to pence. Multiply 9 by 12, the number of pence in a shilling, and bring in the 6d. of the given sum above, makes 114 pence. KEY TO CARD No. 25. Again; how many times 19 in 114? 6 times--place 6 off at the right for a quotient—this is 6 pence-Multiply 19 by 6—place the product under 114–subtract, and nothing remains, RECAPITULATION. In the first quotient you had 1 pound; in the second, 17 'shillings, and in the third, 6 pence. These make for an answer, £ 1 17 6.. LESSON 5.

Multiply 23 by 6m-place the quotient under 147—subtract-the remainder is 9s. to be reduced to pence; multiply 9 by 12, the number of pence in a shilling, and add KEY TO CARD No. 25. to the product the 7 pence in the given sum above: this operation makes 115 pence. Now, how many times 23 in 115? 5 times place 5 in the quotient; this makes 5 pence. Multiply 23 by 5– place the product under 115–subtract—the remainder is 0. RECAPITULATION. Your first quotient was £7; the second 16s. and the third 5d.-making in the whole, for an answer, £7 16 5. LESSON 6. Bought 26 watches for £ 239 4 0, what did each one cost? S.
