Answer 1

НОК{3,4,5} = 3*4*5 = 60 дней, через 60 дней они встретятся
2) 60 : 7 = 8 (остаток 4),значит это будет пятница

Answer 2

Calculating the Next Meeting at the Pool

To calculate when Petya, Vasya, and Kolya will meet again at the pool, we can use the concept of the least common multiple (LCM) of their respective swimming schedules. Petya goes to the pool every 3 days, Vasya every 4 days, and Kolya every 5 days.

The LCM of 3, 4, and 5 will give us the number of days after which they will meet again.

Calculating the LCM: The LCM of 3, 4, and 5 is 60.

Therefore, they will meet again after 60 days.

Determining the Day of the Week

To determine the day of the week when they will meet again, we can use the fact that the days of the week repeat in a cycle of 7 days.

Since 60 is divisible by 7, the remainder when 60 is divided by 7 will give
