The length of the segment AB is 16 dm 8 cm the length of the segment CD is 420 mm.

The length of the segment AB is 16 dm 8 cm the length of the segment CD is 420 mm. How many times is the length of the segment CD less than the length of the segment AB?

We convert the length of the segment AB to millimeters:

16 dm 8 cm = 16 * 100 mm + 8 * 10 mm = 1600 mm + 80 mm = 1680 mm.

Determine how many times the length of the segment CD is less than the length of the segment AB:

1680: 420 = 4 times.

Answer: the length of the segment CD is 4 times less than the length of the segment AB.
