The length of the segment AB is 18. Points C, D are taken on the segment so that AC: CD = 1: 3 CD: CB = 3: 5. Find the length of the segment CD.
1. By the condition of the problem, the segment AB is divided into three segments, the ratio of which is
1: 3: 5.
2. Let’s count how many parts the whole length of the segment AB is.
1+ 3 + 5 = 9.
3. Find how many measures of length are one part if the entire length of the segment is 18.
18: 9 – 2.
4. Let’s calculate the length of the segment CD if it is known that its length is 3 parts.
2 * 3 = 6.
Answer: The length of the CD segment is 6.
