A broken line consists of links of the same length, which can be the number of links if the length of the broken line is 1 meter and the length of the link is 2 dm.

The length of the entire polyline is equal to – 1 meter.

The length of one link is equal to 2 dm.

Let’s determine the number of all links. We write down the solution.

First, you need to translate the length of the entire broken line into decimeters. It turns out the following.

1 m = 10 dm.

Next, we will determine the number of all links. To do this, divide the length of the entire broken line by the length of one link.

1 m: 2 dm = 10 dm: 2 dm = 5.

Therefore, the number of links with a length of 2 decimeters is 5.

Answer: the number of links is 5.
