Write numberin expanded form 12245

10000 + 2000 + 200 + 40 + 5

We get this by times each place by its place value.

For instance lets look at 12245

The 1 is in the 10000 place so we times 1 x 10000 = 10000

The 2 is in the 1000 place so we times 2 x 1000 = 2000

The next 2 is in the 100 place so we times 1 x 100 = 200

The 4 is in the 10 place so we times 4 x 10 = 40

The 5 is in the 1 place so we times 5 x 1 = 5

Now to put it in expanded form just add them like:

10000 + 2000 + 200 + 40 + 5

So the answer is 10000 + 2000 + 200 + 40 + 5

Also to check just add them and it will equal the following:

10000 + 2000 + 200 + 40 + 5 = 12245

10,000 times 2) 100 times 2) 10 times 4) 5 times 1)
