| **The length of the segment DE is 5.6 cm and it is 4 \ 9 of the sum of the segment DE and KM find the length of the segment KM**

Given:

The length of the section DE is 5.6 centimeters.

The DE segment is 4/9 the sum of the DE and KM segment.

Let’s find how many centimeters are only one part of the sum:

5.6: 4 = 1.4 centimeters.

Let’s find what part is the CM segment:

9/9 – 4/9 = 5/9.

Let’s calculate the length of the KM segment:

5 * 1.4 = 7 centimeters.

Answer: the KM segment is 7 centimeters long.
