Question

Quizplus · Accepted Answer

To round to the nearest hundredth, we look at the third decimal place: 5. Since 5 is equal to or greater than 5, we round up the digit in the hundredths place (0) to 1. Therefore, the rounded time is 2.21 minutes. Rounding 2.20535 to the nearest hundredth gives 2.21. Option A is incorrect because rounding up to 2 decimal places would result in a value of 2.22. Option C is incorrect because rounding down to 2 decimal places would result in a value of 2.20. Option D is incorrect because rounding to 3 decimal places is not necessary in this case.
