Which choice correctly shows rounding to the hundredths place?

Romashka-Z-Leto [24]

Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)

Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up.

Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.

Choice D is true. The three decimal values are rounded properly to the correct number of decimal places.

Therefore choice D is the answer
