In the critical lesson, friend were presented to decimal numbers. Decimal places readjust by a element of 10. For example, let"s look at the number "3247.8956" below.

You are watching: Twenty three hundredths as a decimal

 3 x 1000 thousands 2 x 100 hundreds 4 x 10 tens 7 x 1 ones 8 x 0.1 tenths 9 x 0.01 hundredths 5 x 0.001 thousandths 6 x 0.0001 ten-thousandths

A decimal number deserve to have a whole-number part and a fountain part.

 Mixed Number - Expanded kind - Decimal Form = (5 x 10) + ( 7 x 1) + (4 x ) + (9 x ) = 57.49 - whole-number part - - fractional part -

In this lesson, you will learn how to read and write decimals. You might use our Place Value and Decimals Chart (PDF) as a visual reference for the examples presented in this lesson.

Example 1: create each mixed number together a decimal.

 Mixed Number Decimal 52.3000 973.4100 31.2670 1842.0056

Example 2: write each expression as a blended number and as a decimal.

 phrase mixed number decimal five and also three tenths 5.300000 forty-nine and also one hundredth 49.010000 two hundreds sixteen and two hundreds thirty-one thousandths 216.231000 nine thousand, ten and three hundred fifty-nine ten-thousandths 9,010.035900 seventy-six thousand, fifty-three and forty-seven hundred-thousandths 76,053.000470 two hundred twenty-nine thousand and eighty-one millionths 229,000.000081

Look at the blended numbers in the instances above. You will an alert that the denominator of the fractional part is a variable of 10, making it is simple to convert to a decimal. Let"s look in ~ some examples in i m sorry the denominator is not a element of 10.

Example 3: Write each blended number together a decimal.

Analysis: A fraction bar tells us to divide. In bespeak to do this, we must convert or change the fractional part of each blended number to decimal digits. Us will execute this by separating the numerator of each portion by that is denominator.

 Mixed Number Fractional Part Decimal  6.9000  9.7200  167.1250  149.5625 Alternate Method: It need to be provided that some of the fractions above could have been convert to decimal using equivalent fractions. Because that example: Example 4: When asked to write two hundred thousandths as a decimal, three students gave three different answers as shown below. I beg your pardon student had the exactly answer?

Student 1: 200,000.

Student 2: 0.200

Student 3: 0.00002

Analysis: Let"s usage our location value chart to aid us analysis this problem.

 PLACE VALUE and DECIMALS              Student 1 2 0 0 0 0 0 . Student 2 0 . 2 0 0 Student 3 0 . 0 0 0 0 2

Let"s look at the expanded kind of every decimal to aid us discover the correct answer.

 Student Number Fraction Expanded Form Phrase 1 200,000.00000 2 x 100,000 two hundred thousand 2 0.20000  two hundred thousandths 3 0.00002  two hundred-thousandths

As you can see, decimal are called by the place of the critical digit. An alert that in instance 4, the answer given by student 3 was 2 hundred-thousandths. This phrase has actually a hyphen in it. The hyphen is critical piece of information that helps united state read and also write decimals. Let"s look in ~ some more examples.

Example 5: Write each phrase as a decimal.

 phrase analysis fraction decimal three hundred ten thousandths 310 thousandths 0.310 three hundred ten-thousandths 300 ten-thousandths 0.0300

Example 6: compose each expression as a decimal.

 phrase analysis fraction decimal eight hundreds thousandths 800 thousandths 0.800 eight hundred-thousandths 8 hundred-thousandths 0.00008

Example 7: compose each phrase as a decimal.

 phrase analysis fraction decimal seven hundreds millionths 700 millionths 0.000700 seven hundred-millionths 7 hundred-millionths 0.00000007

In instances 5 through 7, us were inquiry to write phrases as decimals. Several of the indigenous in the phrase indicate the place-value positions, and other words in the phrase suggest the digits to be used. Currently let"s look in ~ some instances in which we compose these type of decimals using words.

Example 8: write each decimal utilizing words.

 decimal analysis phrase 0.110 110 thousandths one hundreds ten thousandths 0.0100 100 ten-thousandths one hundreds ten-thousandths

Example 9: write each decimal making use of words.

 decimal analysis phrase 0.400 400 thousandths four hundreds thousandths 0.00004 4 hundred-thousandths four hundred-thousandths

 Example 10: Write the adhering to decimal utilizing words. Roll your mouse over each digit because that help. Answer: The decimal 1,729,405.008365 is created as:

one million, seven hundred twenty-nine thousand, four hundred five and also eight thousand, 3 hundred sixty-five millionths

Summary: You learned how to read and write decimals in this lesson. When writing a blended number as a decimal, the fractional part must be convert to decimal digits. Decimals are named by the place of the critical digit. The hyphen is an essential indicator when reading and also writing decimals. As soon as writing a expression as a decimal, some of the words show the place-value positions, and other words indicate the digits to it is in used.
