Answer 2

To convert 3 cm 9 mm to millimeters (mm), you need to add the equivalent of centimeters to the millimeters.

1 cm = 10 mm

Therefore, 3 cm = 3 * 10 mm = 30 mm

Adding the 9 mm, the total is:

30 mm + 9 mm = 39 mm

So, 3 cm 9 mm is equal to 39 mm.

Now, to convert 5 dm 7 cm to centimeters (cm), you need to add the equivalent of decimeters and centimeters.

1 dm = 10 cm

Therefore, 5 dm = 5 * 10 cm = 50 cm

Adding the 7 cm, the total is:

50 cm + 7 cm = 57 cm

So, 5 dm 7 cm is equal to 57 cm.

Finally, to convert 57 cm to millimeters (mm):

1 cm = 10 mm

Therefore, 57 cm = 57 * 10 mm = 570 mm

So, 5 dm 7 cm is equal to 570 mm.
