Step by step
The question
Question: put 3,071, 3,701, 3,017 in order, from least to greatest.
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
3,701 and 3,071 are the same in the first place.
Look at the hundreds: 7 is more than 0.
So 3,701 is greater than 3,071.
3,071 and 3,017 are the same in the first 2 places.
Look at the tens: 7 is more than 1.
So 3,071 is greater than 3,017.
3 Write them in order
From least to greatest: 3,017 < 3,071 < 3,701.
4 Check
On a number line, smaller numbers are to the left.
Left to right: 3,017, 3,071, 3,701.
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.
