Final answer:
The number 0.16 is already in the requested format of two decimal places, so it remains unchanged at 0.16. No rounding is needed in this case as it already meets the criteria for significant figures.
Step-by-step explanation:
The question asks about rounding 0.16 to two decimal places. However, since the number is already at two decimal points, there's actually no need for rounding — the number remains 0.16. When discussing significant figures, it's important to note that if additional precision is not present or necessary, the value remains the same. For example, when rounding to the nearest hundredths place, a number such as 18.006 would be rounded to 18.01 since that is the least precise figure among the given numbers. Alternatively, when expressing numbers in scientific notation, such as 2.4 x 10-2, correctly moving the decimal place can also be crucial for proper significant figures.
