1. Write 23,851 as 2 ten thousands, 3 thousands, 8 hundreds, 5 tens and 1 one.. 2. The whole number 159 in expanded form as follows: 159 = (1 x 100) + (5 x 10) + (9 x 1).
.......................................................................................................................................................................................... The expanded form of a decimal number is the number written as the sum of its whole number and decimal place values. 4 + 0.7 + 0.05 + 0.003 is the expanded form of the number 4.753.100 + 6 + 0.08 is the expanded form of the number 106.08. Example:  Expanded Form is a way to break up a number to show how much each digit in the number represents. In other words, expanded form is the method of pulling a number apart and expressing it as a sum of the values of each digit. The best way to identify the expanded form of a number is to simply write the number in words.  Instructions. Write a number in expanded form using both numbers and words. For example, write 23,851 as 2 ten thousands, 3 thousands, 8 hundreds, 5 tens and 1 one.. This illustrates what place value each numeral holds within the number. Express the number in expanded form using numbers. Using the same number, you would write 20,000 + 3,000 + 800 + 50 + 1.. Add decimal numbers to a number and express them in expanded form also. For example, write 6,923.47 in expanded form using words by writing 6 thousands, 9 hundreds, 2 tens, 3 ones, 4 tenths and 7 hundredths.. Expanded Form is a way to write numbers by adding the value of its digits. Example: 1,000 + 900 + 50 + 4 = 1,954. Example 1: Write and Read the number 6,174.  Expanded Form. According to our work above, when we write the number 521, what the number really means is that we have the total of 500 + 20 + 1. We've expanded the number to show the value of each of its digits. When we expand a number to show the value of each digit, we're writing that number in expanded form. Let's try it with a different, bigger number: 1,234,567. We'll start by placing the number's digits in the place value chart. Now, let's use the chart to determine the value of each digit.  The place value of numbers is crucial to students' understanding of mathematical principles. When students learn the place value of any number, they can go on to solve equations with numbers. Learning to write numbers in expanded form is an exercise that illustrates and teaches place value to students. Add decimal numbers to a number and express them in expanded form also. For example, write 6,923.47 in expanded form using words by writing 6 thousands, 9 hundreds, 2 tens, 3 ones, 4 tenths and 7 hundredths.. We can write the whole number 159 in expanded form as follows: 159 = (1 x 100) + (5 x 10) + (9 x 1). Decimals can also be written in expanded form. Expanded form is a way to write numbers by showing the value of each digit. This is shown in the example below. Example 4: Write each decimal in expanded form.
