Answer 2

To convert the given measurements from decimeters (dm) to millimeters (mm), you need to multiply the values by 10.

1 dm = 10 cm = 10 * 10 mm = 100 mm So, 1 dm is equal to 100 mm.

4 dm = 40 cm = 40 * 10 mm = 400 mm Therefore, 4 dm is equal to 400 mm.

Thus, the conversions are as follows: 1 dm = 100 mm 4 dm = 400 mm
