Answer 3

Comparing Lengths

To compare the lengths, we have 2 dm and 8 cm, and we want to determine if it's greater or less than 82 cm.

Conversion to Centimeters

First, let's convert 2 dm to cm: - 1 dm = 10 cm - 2 dm = 2 * 10 cm = 20 cm

So, 2 dm is equal to 20 cm.

Adding the Lengths

Now, we add 20 cm and 8 cm: - 20 cm + 8 cm = 28 cm

Comparison

28 cm is less than 82 cm.

Therefore, 2 dm and 8 cm is less than 82 cm.
