135-15=120 (шк)

120:2=60 (шк) на первом теплоходе

60+15=75 (шк) на втором

 

Answer 3

Problem Analysis

We have a group of 135 schoolchildren who are going on an excursion. They will be divided into two boats, with one boat having 15 fewer people than the other. We need to determine how many schoolchildren were on each boat.

Solution

Let's assume that the number of schoolchildren on the first boat is x. According to the problem, the second boat has 15 more people than the first boat, so the number of schoolchildren on the second boat is x + 15.

The total number of schoolchildren is given as 135, so we can write the equation:

x + (x + 15) = 135

Simplifying the equation:

2x + 15 = 135

Subtracting 15 from both sides:

2x = 120

Dividing both sides by 2:

x = 60

Therefore, there were 60 schoolchildren on the first boat, and on the second boat, there were 60 + 15 = 75 schoolchildren.

Answer

There were 60 schoolchildren on the first boat, and 75 schoolchildren on the second boat.
