Thus and have a common denominator. We have seen that, when two or more fractions have a common denominator, they may be added and subtracted as well as whole numbers. We add or subtract the numerators, and write their sum or difference over the common denominator. The first part of the process in the above examples was to reduce them to ä common denominator. 76. Reduce , and to a common denominator. Note. They may be reduced to twelfths. If it cannot be immediately seen what number must be the common denominator, it may be found by multiplying all the denominators together; for that will always produce a number divisible by all the denominators. 77.

Mr. F. said he would give of a pine-apple to Fanny, and 3 to George, and the rest to the one that could tell how to divide it, and how much there would be left. But neither of them could tell; so le kept it himself. Could you have told if you had been there? How would you divide it? How much would be left ? 2. A man sold 14 bushels of wheat to one man, 4 bushels to another; how many bushels did he sell to both ? 3. A man bought 6 bushels of wheat at one time, and 21 at anoiher; how much did he buy in the whole ? 4. A man bought 73 yards of one kind of cloth, and 67 yards of another kind: how many yards in the whole ? 5. A man bought of a barrel of flour at one time, 27 barrels at another, and 63 at another; how much did he buy in the whole ? 6. A man bought one sheep for 4ş dollars, and another for 58 dollars; how much did he give for both ? 7. There is a pole standing, so that of of it is in the mud, and of it in the water, and the rest out of the water ; how much of it is out of the water? * Ans. 1. 8. A man having undertaken to do a piece of work, did į of it the first day, { of it the second day, and I of it the third day, how much of it did he do in three days ?' 9. A man having a piece of work to do, hired two men and a boy to do it. The first man could do į of the work in a day, and the other of it, and the boy } of it; how much of it would they all do in a day? Note. By dividing a line into halves, and then into fourths, it will be seen that 4 is the same as 1, a line divided into balves and then into sixths, will show that is the same as , and as 3; 4, 8, can therefore be reduced to , and to g. This is called reducing fractions to their lowest terms. It is done by dividing the greatest number that will divide it without a renainder. 1. Reduce to its lowest terms. 2. Reduce so to its lowest terms. 3. Reduce to its lowest terms. 4. Reduce to its lowest terms. 5. Reduce ji to its lowest terms. 6. Reduce to its lowest terms. to its lowest terms. 8. Reduce je to its lowest terms. 9. Reduce to its lowest terms. 10. Reduce to its lowest terms. 11. Reduce á to its lowest terms. 12. Reduce to its lowest termis. 13. Reduce ji to its lowest terms. 14. Reduce 41 to its lowest terms. Note. It will be seen by the above section that if both the numerator and denominator be multi plicd by the same number, the value of the fraction will not be altered; or if they can both be divided by the same number without a remainder, the fraction will not be altered. * If this article should be found too difficult for the pupil, he may omit intill after the pext section. 7.
