Final answer:
To approximate the value of 15 to the nearest hundredth, round the digit in the hundredths place based on the digit in the thousandths place.
Step-by-step explanation:
To approximate the value of 15 to the nearest hundredth, we look at the digit in the thousandths place, which is 5 in this case. Since 5 is greater than or equal to 5, we round up the digit in the hundredths place by adding 1. Therefore, the value of 15 rounded to the nearest hundredth is 15.01.
