#### Steps to Solve

1. Identify the place values

Look at the number 84. The digit in the tens place is 8 and the digit in the ones place is 4.

1. Apply rounding rules

Since we want to round to the nearest ten, we need to focus on the ones place (4). The rounding rule states:

• If the ones digit is 5 or more, round up.
• If the ones digit is less than 5, round down.

In this case, since the ones digit is 4, which is less than 5, we will round down.

1. Determine the rounded number

When we round down, we keep the digit in the tens place the same (8) and replace the digit in the ones place with 0.

Thus, rounding 84 to the nearest ten gives us:

$$80$$

• Another mistake could be not replacing the ones digit with a zero after rounding correctly.
