Solution Explanation:

#### Step 1: Understanding Rounding to the Nearest Ten
Rounding a number to the nearest ten means determining whether the number is closer to the lower or higher multiple of ten. Here are the rules:
- If the digit in the ones place (the rightmost digit) is 5 or greater, round up to the next multiple of ten.
- If the digit in the ones place is less than 5, round down to the previous multiple of ten.

#### Step 2: Applying the Rules
We will go through each number provided in the image and apply the rounding rules.
