Final answer:
To determine how many times to move the decimal when multiplying 0.73 by 2.52, add the number of decimal places from both numbers: 0.73 has two and 2.52 has two, totaling four. So, move the decimal four times to the left in the final answer.
Step-by-step explanation:
When multiplying 0.73 by 2.52, you combine the decimal places of both numbers to determine how many times to move the decimal point. Since 0.73 has two decimal places and 2.52 has two decimal places, you add these together to get four decimal places total. Therefore, you would move the decimal point 4 times to the left in the final answer.
To understand this better, consider the example of multiplying 2.4 by 100. You move the decimal point 2 places to the right to obtain 240. This same principle applies when you have two numbers with decimals being multiplied. Moving the decimal point correctly ensures that the magnitude of your answer reflects the precision of the numbers you started with.
