Step-by-step solution

To solve this problem, we'll follow these steps:

  • Identify the number of decimal places in each factor
  • Sum the decimal places of the factors
  • Place the decimal point in the product accordingly
  • Confirm with the provided choices

Step 1: Let's determine the decimal places:
The number 2.372.37 has 2 decimal places.
The number 1.101.10 has 2 decimal places.

Step 2: Calculate the total decimal places:
The sum of the decimal places in both numbers is 2+2=42 + 2 = 4.

Step 3: Position the decimal point in the product:
The result of 2.37×1.102.37 \times 1.10 is displayed as 2607.
We need to place the decimal point such that the result contains 4 decimal places in total, starting from the rightmost digit.

Step 4: Apply the decimal adjustment:
Starting from the right, place the decimal point 4 places from the right: 2.6072.607.

Therefore, the correct position of the decimal point in the product is 2.6072.607.
