📝 Explanation:
This worksheet helps students practice dividing by 10, which is a foundational skill in understanding place value and decimals. The key concept is that dividing by 10 reduces the value of each digit by a factor of 10, effectively shifting the digits one place to the right.
For example:
- 630 becomes
63 because the 6 (hundreds) moves to tens, and 3 (tens) moves to ones.
- 70 becomes
7 because 7 tens divided by 10 is 7 ones.
This pattern works for any number divisible by 10.
