Question

Сумма 3 чисел равна 300 2 число в 2 раза больше первого А 3 число 3 раза больше первого Найдите второе число​

Answer 1

Ответ:

Примем первое число за х, тогда второе за 2 х и третье за 3 х

х + 2х + 3х = 300

6х = 300

х = 50

2х = 100

тоесть второе число равно 100

Answer 2

Let's solve this problem step by step.

Let's assume the first number is x. According to the given information, the second number is twice the first number, so the second number is 2x. Similarly, the third number is three times the first number, so the third number is 3x.

The sum of the three numbers is 300, so we can set up the equation:

x + 2x + 3x = 300

Combining like terms, we have:

6x = 300

Now, we can solve for x by dividing both sides of the equation by 6:

x = 300 / 6

x = 50

Therefore, the first number is 50.

The second number is twice the first number:

2x = 2 * 50 = 100

So, the second number is 100.
