Explanation:

Step1: Recall dilation formula

When a segment is dilated by a scale factor \( k \), the length of the new segment is \( k \times \) original length. Here, scale factor \( k=\frac{1}{3} \), original length \( NO = 15 \).

Step2: Calculate \( N'O' \) length

Multiply the original length by the scale factor: \( N'O'=\frac{1}{3}\times15 \).
Simplify: \( \frac{1}{3}\times15 = 5 \).
