Problem Analysis

To solve this problem, we need to determine the number of children who did not receive certificates and did not become winners in the competition. We are given that 86 people participated in the competition, 5 of whom were schoolchildren. Additionally, two-thirds of the remaining children received certificates.

Solution

Let's break down the problem step by step:

1. Total number of participants: 86 2. Number of schoolchildren who won: 5 3. Remaining participants: 86 - 5 = 81 4. Two-thirds of the remaining participants received certificates: (2/3) * 81 = 54 5. Number of children who did not receive certificates and did not become winners: 81 - 54 = 27

Therefore, 27 children did not receive certificates and did not become winners in the competition.

Answer

The number of children who did not receive certificates and did not become winners in the competition is 27.
