Review for Mastery Decimals and Fractions

You can write decimals as fractions or mixed numbers. A place value chart will help you read the decimal. Remember the decimal point is read as the word “and.”

To write 0.47 as a fraction, first think about the decimal in words.

0.47 is read “forty-seven hundredths.” The place value of the decimal tells you the denominator is 100.

0.47 = 47100

To write 8.3 as a mixed number, first think about the decimal in words.

8.3 is read “eight and three tenths.” The place value of the decimal tells you the denominator is 10. The decimal point is read as the word “and.”

8.3 = 3810

Review for Mastery Decimals and Fractions (continued)

Fractions and mixed numbers can be written as decimals. To write 14 as a decimal, first think about the expression in words.

14 means “1 divided by 4.”

Then do the division. 0.25 is a terminating decimal

because it has an end 14 = 0.25

A number that contains a whole number and a fraction is called a mixed number. 123

is an example of a mixed number. To

write 123 as a decimal, first think about the expression in words.

123 means “2 and 1 divided by 3.” Keep 2 as the whole number.

Then do the division. 1 ⎟ 3 = 0.33 . . ., or 0.3.

0.3 is a repeating decimal because it does not end.

So, 123

= 2.3 .

Write each fraction or mixed number as a decimal.

Reading Strategies Focus on Vocabulary

The word repeating means something happening over and over. A church bell that chimes every hour is an example of a repeating sound.

The word terminating means something that ends. The sixth grade class party will be terminating at 10:00 P.M.

Fractions can be written as either terminating or repeating decimals. In a repeating decimal, sometimes one digit repeats and sometimes more than one digit repeats. 13 means 1 ⎟ 3 1

4 means 1 ⎟ 4

The bar over 3 means 0.25 is a decimal the 3 keeps repeating. that terminates.

Write “terminating decimal” or “repeating decimal” for each. If the decimal repeats, write which digit or digits repeat.
