I begin as in Short Division of whole numbers, and say, 2 is contained in 15£, 7 (£) times, and 1£ over, writing down the 7 times. Q. What do you do with the 1£ over ? A. 1£20 s. which I join or carry to the 3 s., making 23 s. Q. How do you proceed then, to get the 11 s.? A. I say, 2 in 23, 11 times, and I s. over, writing down the 11 s. underneath. Q. How do you get the 10 d.? A. The 1 s. over being equal to 12 d., I join or carry it to 8 d., making 20 d.; then, 2 in 20, 10 times. From these illustrations we derive the following RULE. Q. At which hand do you begin to divide, and how do you proceed? A. With the highest denomination, and divide as in Simple Division. Q. If you have a remainder, how do you proceed? A. Find how many of the next lower denomination this remainder is equal to, which add to the next denomination; after which divide as in whole numbers. PROOF. Q. What is the proof? A.

Three sixths. Three eighths. Eight twelfths. Q. What are such expressions as these called? A. Fractions. Q. When, then, any whole thing, as an apple, a unit, &c. is broken or divided into equal parts, what are these parts called?' A. Fractions. Q. Why called fractions? A. Because fraction signifies broken. Q. You have seen, that, when any whole thing is divided into parts, these parts are called thirds; into 4 parts, called fourths: what then, does the fraction take its name or denomination from? A. From the number of parts into which any thing is divided. Q. When an apple is divided into 6 parts, and you are desirous of giving away 5 parts, how would you express these parts ? A. §. Q. What is the 6 (in §) called? A. The denominator. Q. Why so called? A. Because it gives the name or denomination to the parts. |
