3) 180+ 120 = 300 человек- участвовало в конкурсе.
Ответ: 300 человек участвовало в конкурсе

Answer 2

Calculation of Total Number of Participants in the Singing Competition

To calculate the total number of participants in the singing competition, we are given that the participants were divided into two groups in a ratio of 3:2 for auditions on different days. It is also mentioned that the smaller group consisted of 120 people.

Let's denote the total number of participants as x.

According to the given ratio, the larger group would consist of 3/5 of the total participants, and the smaller group would consist of 2/5 of the total participants.

Based on this information, we can set up the following equation:

(2/5) * x = 120

To find the value of x, we can solve this equation:

(2/5) * x = 120

Multiplying both sides of the equation by 5/2:

x = 120 * (5/2)

Simplifying the equation:

x = 300

Therefore, the total number of participants in the singing competition was 300 people.
