Step-by-step solution for: 3RD GRADE MATH - ROUNDING NUMBERS TO NEAREST TEN-THOUSANDS ...
Let's solve this "Rounding numbers to the nearest ten thousand" worksheet step by step. The goal is to round each number to the nearest ten thousand, which means we're looking at the ten thousands place and checking the digit in the thousands place to decide whether to round up or down.
---
- Look at the thousands digit (the 4th digit from the right).
- If it's 5 or more, round up.
- If it's less than 5, round down.
- Then, replace the last four digits with zeros.
---
We’ll go through each problem one by one.
---
- Thousands digit = 5 (in 25,646)
- Since 5 ≥ 5 → Round up
- 25,646 → 30,000
✔ Answer: 30,000 (already circled — correct!)
