A man wished to give 4 of a bushel of wheat to one man, and f of a bushel to another; but he could not tell how to divide it. Another man, standing by, advised him to divide the vhole bushel into six equal parts first, and then take of them for one, and of them for the other. How many parts did he give to each ? How many to both ? How many had he left ? 14. 1 is how many ? ; is how many ? 1 and are how many ? 15.

A man, having two bushels of grain to distribute among his labourers, wished to give 4 of a bushel to one, and of a bushel to another, and the rest to a third; but was at a loss to tell how to divide it; at last he concluded to divide each bushel into six equal parts, or sixths, and then to distribute those parts. How many sixths did he give to each 22. is how many ? 23. A man had a horse, and a cow, and a sheep. The horse would eat of a load of hay in the winter, the cow }, and the sheep .

A boy, having a pound of almonds, said he intended to give of them to his sister, and to his brother, and the rest to his mamma. His mamma, smiling, said she did not think he could divide them so. O I can, said he; I will first divide them into twelve equal parts, and then I can divide them well enough. Pray how many twelfths did be give to each? 29. f is how many 11? is how many ? and are how many ? 30. Mr. Goodman, having a pound of raisins, said he would give Sarah $, and Mary 5, and James of them; and he told Charles he should have the rest, if he could tell how to divide them. Well, said Charles, I would first divide the whole into twelve equal parts, and then I could take , and 1, and of them. How many twelfths would each have ? 31. and 1 and 4 are how many I? 32. George bought a pine-apple, and said he would give 1 of it to his papa, and to his mamma, and it to his brother James, if he could divide it. James took it, and cut it into twenty equal pieces, to then distributed them as George had desired. How many twentieths did he give to each? 33. t is how many ? * is how many ? & is how many ito?

When the denominators in two or more fractions are the same, the fractions are said to have a common denominator. Thus $ and i 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 a common denominator. 76. Reduce in 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. Reduce g and if to a common denominator. 78. Reduce , and and to a common denominator. 79. Reduce f and } to a common denominator. 80. Reduce it and į to a common denominator. |
