Divide the number 81 into units and tens.

To solve this problem, we need to break down the number 81 into its tens and units components using the decimal structure:

• Step 1: Identify the number. Here, the number given is 81.
• Step 2: Recognize the structure of numbers in decimals - in a two-digit number, the first digit represents the tens place, and the second digit represents the units place.
• Step 3: Decompose 81 into tens and units:

For the number 81:

• The tens digit is the first digit: $8$.
• The units digit is the second digit: $1$.
• Thus, 81 can be expressed as 8 tens and 1 unit.

We conclude that the decomposition of 81 is into 8 tens and one unit.
