16. Write one sixth; four sixths; five sixths.

17. How many fifths are there in anything? How many sixths?

18. Read the following fractions and give the

19. Name the numerators and the denominators of the following fractions:

1. Add 1 ft. and ft. Write the answer. 2. How many halves are in 11? Write the answer. 3. Add 3 ft. and ft. Write the answer.

4. How many halves are in 31? Write the answer. 5. If you add 5 feet and foot, how many feet will you have? Write the answer.

6. How many halves are in 5? Write the answer. 7. Numbers such as 11, 21, and 51⁄2 are called mixed numbers.

}+}=? }+{= ? }+{}=? {+}=? }+}= ? }+}=? {+}=? }+}=?

4. Add the following columns. When possible, reduce

the answers to whole numbers or to mixed

numbers.

In the figures given below you see that when is added to the halves are changed to fourths so that the answer may be expressed as fourths.

In adding fourths to eighths, the fourths are changed to eighths as in this example:

Before fractions can be added, they must

be changed to the same denominators.

6. Add the following fractions. Tell what denominators you have to change.

48141

7. Add, changing halves to fourths or eighths, and
