🔍 Explanation:
This worksheet tests
place value understanding. Each number is broken down into its component parts (like ten-thousands, thousands, hundreds, tens, ones), and you add them to get the
standard form.
For example:
- $50000$ → 5 in the
ten-thousands place
- $3000$ → 3 in the
thousands place
- $200$ → 2 in the
hundreds
- $60$ → 6 in the
tens
- $9$ → 9 in the
ones
So, putting it together:
53,269
You can apply this logic to all problems.
