How do you find the decimal portion of a decimal?

Answer 1

Decimals are another way of expressing fractions. I like to use American How_do_you_find_decimalsas a teaching tool. For example, our fifty-cent coin is a half dollar. But written as a decimal, it's 0.5 or 0.50. The same idea applies to our twenty-five-cent coin, the quarter, which is decimal 0.25.

Now, to your question: These decimal numbers are all fractions. for example,

the quarter coin is

25

----- of a dollar, spoken "twenty-five hundredths of a dollar."

100

The fifty-cent coin is

50

---- of a dollar, spoken "fifty hundredths of a dollar."

100

Any fraction can be converted to a decimal by division. In most countries, the expression of a fraction, such as

7

---- can be read either as "seven eighths" or as "seven divided by eight."

8

This means that the conversion to decimal can be accomplished by dividing 7 by eight, the result of which is 0.875. This fraction may be pronounced as "eight hundred seventy-five one thousandths," but that's very difficult, so most people just read the digits and say "decimal eight seven five" or "How_do_you_find_decimalseight seven five."

Decimals aren't limited to numbers less than one. If you have a dollar and a half, this can be converted to an improper fraction (where the top number is bigger than the bottom number) that looks like

3

--- dollars. Next, by doing the division, you see it as 1.5 dollars or 1.50 dollars
