The question
Question: write 381 in expanded form.
Write 381 in expanded form
1 Show it with blocks
381 is 3 hundreds, 8 tens, 1 one.
2 Put the digits in the chart
Each digit has a place.
3 Find the value of each digit
The 3 is 3 hundreds.
That is 300.
The 8 is 8 tens.
That is 80.
The 1 is 1 one.
That is 1.
4 Write it as a sum
Expanded form means we write the value of each digit, with + between them.
381 = 300 + 80 + 1
5 Check
We add them back: 300 and 80 and 1 make 381.
Yes!
It works.
300 + 80 + 1 = 381
Let's look back.
First: show it with blocks.
Then: put the digits in the chart.
Then: find the value of each digit.
Then: write it as a sum.
Last: check.
Answer
381 = 300 + 80 + 1
