Коля,Дима и Саша собрали вместе 30 грибов,Дима нашел в 2 раза ббольше грибов, чем Коля, а Коля в 3 раза меньше чем Саша. Сколько грибов нашел каждый из них?Сделай чертеж к задаче и реши ее?

Answer 1

У коли х грибов, тогда у димы- 2х, а у Саши - 3х. Имеем уравнение:
х+2х+3х=30
6х=30
х=30:6
х=5 - у коли;
у димы - 5•2=10
у саши - 5•3=15.

Problem Analysis

We are given that Kolya, Dima, and Sasha collected a total of 30 mushrooms. Dima found twice as many mushrooms as Kolya, and Kolya found three times fewer mushrooms than Sasha. We need to determine how many mushrooms each of them found.

Solution

Let's assume that Kolya found x mushrooms. Based on the given information, we can determine the number of mushrooms found by Dima and Sasha.

- Dima found twice as many mushrooms as Kolya, so Dima found 2x mushrooms. - Kolya found three times fewer mushrooms than Sasha, so Sasha found 3x mushrooms.

The total number of mushrooms found is the sum of the mushrooms found by each person, which is 30.

Therefore, we can write the equation: x + 2x + 3x = 30

Simplifying the equation: 6x = 30 x = 5

So, Kolya found 5 mushrooms, Dima found 2 * 5 = 10 mushrooms, and Sasha found 3 * 5 = 15 mushrooms.

Solution Verification

Let's verify our solution by substituting the values back into the equation: 5 + 10 + 15 = 30

The sum is indeed 30, which confirms that our solution is correct.

Summary

Based on the given information, Kolya found 5 mushrooms, Dima found 10 mushrooms, and Sasha found 15 mushrooms.
