Answer:

What is 16.00 to 1 decimal place?" is the same as asking, "What is 16.00 rounded to one decimal point?" or "How to round 16.00 to one decimal place."

The main point (pun intended), is that you want to round 16.00 to one digit or place after the decimal point. Thus, we want to eliminate the last digit in 16.00. To eliminate the last digit, we use the following One Decimal Place rules to get the answer:

One Decimal Place Rule #1: If the last digit in 16.00 is less than 5, then remove the last digit.

One Decimal Place Rule #2: If the last digit in 16.00 is 5 or more and the second to the last digit in 16.00 is less than 9, then remove the last digit and add 1 to the second to the last digit.

One Decimal Place Rule #3: If the last digit in 16.00 is 5 or more and the second to the last digit in 16.00 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.

When rounding 16.00 to one decimal place we use One Decimal Place Rule #1. Therefore, the answer to "What is 16.00 rounded to 1 decimal place?" is:

Final answer:

To express the number 16 to 1 decimal place, add a decimal and one zero to become 16.0. This format indicates that the number is accurate to one decimal place, which is important for expressing precision in measurements and calculations.

Step-by-step explanation:

When asked to express the number 16 to 1 decimal place, we are being asked to format the number so that it only has one number after the decimal point. In this case, since 16 is a whole number, expressing it to 1 decimal place simply means adding a decimal point and one zero after it, to become 16.0. This ensures the number is shown to the proper decimal place as requested.

It's key to remember that for whole numbers shown to a specific decimal place, place-holding zeros must be used. While calculators can provide precise calculations, the human operator needs to decide the number of significant figures and decimal places to report based on the desired precision.

Furthermore, working with scientific notation adheres to the principle that there should be only one digit to the left of the decimal point, which is how we'd start to express a number like 16, which would become 1.6 × 10² in scientific notation.
