Step by step
The question
Question: put 2,468, 2,486, 2,648 in order, from greatest to least.
1 Line up the places
We line up the ones under the ones, the tens under the tens, and so on.
2 Compare from the left
2,648 and 2,486 are the same in the first place.
Look at the hundreds: 6 is more than 4.
So 2,648 is greater than 2,486.
2,486 and 2,468 are the same in the first 2 places.
Look at the tens: 8 is more than 6.
So 2,486 is greater than 2,468.
3 Write them in order
From greatest to least: 2,648 > 2,486 > 2,468.
4 Check
On a number line, smaller numbers are to the left.
Left to right: 2,468, 2,486, 2,648.
The same order.
Yes!
It works.
Let's look back.
First: line up the places.
Then: compare from the left.
Then: write them in order.
Last: check.
