Place Value Chart
Consider 345,672:
| Hundred Thousands | Ten Thousands | Thousands | Hundreds | Tens | Units |
|---|---|---|---|---|---|
| 3 | 4 | 5 | 6 | 7 | 2 |
Therefore:
345,672 = 300,000 + 40,000 + 5,000 + 600 + 70 + 2
Reading Large Numbers
128,450
is read as:
One hundred and twenty-eight thousand, four hundred and fifty.
