Answer 2

Problem Analysis

We are given that Ivan had 6 times fewer mandarins than Petya, and Petya had 15 more mandarins than Ivan. We need to find the number of mandarins each person had.

Solution

Let's assume the number of mandarins Ivan had as 'x'. According to the problem, Petya had 6 times more mandarins than Ivan, so Petya had 6x mandarins. Additionally, Petya had 15 more mandarins than Ivan, so we can set up the following equation:

6x - 15 = x

Now, let's solve this equation to find the value of x, which represents the number of mandarins Ivan had.

Solving the Equation

To solve the equation, we'll isolate the variable 'x' on one side of the equation.

6x - x = 15

Simplifying the equation:

5x = 15

Dividing both sides of the equation by 5:

x = 3

Therefore, Ivan had 3 mandarins and Petya had 6 * 3 = 18 mandarins.

Answer

Ivan had 3 mandarins, and Petya had 18 mandarins.
