Lesson 3 Section 2
HOW TO NAME OR READ A DECIMAL
Ignore the decimal point and read 038 as the whole number "Thirty-eight." The last digit, 8, falls in the thousandths place.
When we read .038 as "Point 0, 3, 8," that is "spelling" the number, which is often convenient. But its name is "Thirty-eight thousandths."
Ignore the decimal point, and read 002135 as the whole number 2,135 ("Two thousand one hundred thirty-five" Lesson 2, Question 4). The last digit 5 is in the millionths place.
This is called a mixed number. The decimal point separates the whole number 14 on the left, from the decimal fraction on the right. In a mixed number, we read the decimal point as "and."
Example 4. Write these in numerals:
a) Two hundred four thousand
b) Two hundred four thousandths
c) Two hundred and four thousandths
Example 5. Write in words: $607.08
Answer. Six hundred seven dollars and eight cents.
Save "and" for the decimal point.
Note that cents means hundredths. (Centum in Latin means 100.) 1 cent is the hundredth part of one dollar. We write 1 cent either as
$.01 or 1¢.
When we write the cent sign ¢, we do not write a decimal point.
Example 6. Write "eighty cents" using the dollar sign $ and using the cent sign ¢.
Answer. $.80 80¢
