Let's solve the problem step by step.
Task:
Round each number to the
nearest 10.
---
Rule for Rounding to the Nearest 10:
- Look at the
ones digit (the last digit).
- If it is
5 or greater, round
up.
- If it is
less than 5, round
down.
We will apply this rule to each number.

Left Column:
1.
2,252
- Ones digit: 2 → less than 5 → round down
→
2,250
2.
3,333
- Ones digit: 3 → less than 5 → round down
→
3,330
3.
1,121
- Ones digit: 1 → less than 5 → round down
→
1,120
4.
10,245
- Ones digit: 5 → equal to 5 → round up
→
10,250
5.
523,215
- Ones digit: 5 → round up
→
523,220
6.
571,268
- Ones digit: 8 → greater than 5 → round up
→
571,270
7.
16,164
- Ones digit: 4 → less than 5 → round down
→
16,160
8.
6,690
- Ones digit: 0 → less than 5 → round down
