The experimental primary school conducted a survey on students' breakfast eating situation. The results are as follows: 1204 people eat breakfast every day, accounting for 86% of the whole school. It cannot be guaranteed to eat breakfast every day.

The number of people in the whole school: 1204 / 86% = 1400 people

Because 86% of the people do not eat breakfast every day, it cannot be guaranteed that what they eat every day is: 1 - 86% = 14 %

So the number of people eating breakfast is: 1400 * 14% = 196 people
