Let's solve the rounding problems step by step based on the rules provided.

Rounding Rules Recap:

- Rule 1: If the digit to the right of the rounding digit is 1, 2, 3, or 4, do not round up. Keep the rounding digit the same.
- Rule 2: If the digit to the right is 5, 6, 7, 8, or 9, round up by adding 1 to the rounding digit.
- All digits to the right of the rounding digit become 0.

We are rounding to the nearest 10, so we focus on the tens place and look at the ones digit (the digit to its right).

✔ Explanation Recap:
- Always identify the tens digit as the rounding digit.
- Look at the ones digit (to the right).
- If it’s 0–4, keep the tens digit the same.
- If it’s 5–9, increase the tens digit by 1.
- Replace all digits to the right with 0.
