CPM Homework Help : MC2 Problem 1-92

The value of a decimal becomes clearer when the place value is spoken or written as the number it names. For example, $0.1$ makes more sense if it is read as "one-tenth" rather than "zero point one."

Write the following numbers in words so that the place value can be identified.
$0.4$
$1.3$
$0.56$
$2.008$
Now reverse your thinking. Write the decimals that go with the following words.

thirty-five hundredths
three and two-tenths
six-hundredths

Help (a):

Make sure to pay attention to the last digit place of the decimal value. Use the chart to the right for guidance.

Step 1(a):

Look to see if there is a number to the left of the decimal; if so write it out. If there is no number to the left of the decimal, skip to step $3$ .

Step 2(a):

Include 'and' for the decimal point if there is a number to the left of the decimal.

Step 3(a):

Write out the number to the right of the decimal up to the last digit. Write the place value of the last digit.

Example (a):

$0.64 =$ sixty-four hundredths

With these steps, try writing each number in words.

Help (b):

Refer to part (a) for help with decimal places.

Hint (b):

Consider the significance of the place value identified by the last word.

Example Answer (b):

thirty-five hundredths $= 0.35$
