Given the following exercise, find the correct place of the decimal point:
To address this problem, we must first carry out the multiplication between and , removing the decimals temporarily to simplify the process and then adjust for them correctly in the final product.
Step 1: Convert the decimals to whole numbers.
Rewrite as (by multiplying by ) and as (by multiplying by ).
Step 2: Multiply these whole numbers.
Calculate .
Step 3: Determine where the decimal point should be placed in the result.
- The original number has 1 decimal place.
- The original number has 2 decimal places.
Thus, the total number of decimal places required is .
Step 4: Apply these decimal places to the product.
Move the decimal point three places from the right in to get .
Therefore, the correct placement of the decimal point in the product is .
Consequently, the choice corresponding to this solution is:
