To solve the problem, let's break it down step-by-step:
1. Identify the Numbers to Divide:
Carson wants to divide 128 by 3.2.
2. Perform the Division:
When you divide 128 by 3.2, you get 40.0. This means:
[tex]\[ 128 \div 3.2 = 40.0 \][/tex]
3. Analyze the Result:
The result of the division is 40.0. The first digit in this number is 4.
4. Determine the Place Value:
To determine the place value of the first digit, we look at the whole number part of the result. In 40.0, the digit '4' is in the tens place.
Therefore, the place value of the first digit in Carson's answer is:
- tens
So, the correct option is:
[tex]\[ \text{O tens} \][/tex]
