Question

Купили 12 шариков - желтых, синих и красных. Желтых в 8 раз больше чем синих. Сколько красных шариков купили? (Помогите пожалуйста решить...) Ответ должен быть - 3.

Answer 1

12-8=4
1 крас.3 син.
2 крас.2 син.
3 крас.1 син.

Answer 2

Всего шариков 12.
Жёлтых может быть в 8 раз больше синих в двух случаях: Синих 1 шарик, соответственно жёлтых 8, либо и жёлтых и синих по 0 шаров.
В первом случае, мы получаем 12-8-1=3-количество красных шаров.
Во втором случае мы получаем:12-0-0=12- количество красных шаров.

Answer 3

Problem Analysis

We are given that 12 balloons were purchased, consisting of yellow, blue, and red balloons. The number of yellow balloons is 8 times greater than the number of blue balloons. We need to determine the number of red balloons that were purchased.

Solution

Let's assume the number of blue balloons is x. According to the given information, the number of yellow balloons is 8 times greater than the number of blue balloons. Therefore, the number of yellow balloons is 8x.

We know that the total number of balloons purchased is 12. So we can write the equation:

x + 8x + number of red balloons = 12

Simplifying the equation, we have:

9x + number of red balloons = 12

Since we are looking for the number of red balloons, we can isolate the variable:

number of red balloons = 12 - 9x

To find the number of red balloons, we need to substitute the value of x into the equation. Let's solve for x.

Solving for x

Unfortunately, the search results provided by You.com do not contain the specific information needed to solve this problem. However, we can still proceed with the given information.

Since the number of yellow balloons is 8 times greater than the number of blue balloons, we can set up the equation:

8x = number of yellow balloons

We also know that the total number of balloons is 12, so we can write:

x + number of yellow balloons + number of red balloons = 12

Substituting the value of 8x for the number of yellow balloons, we have:

x + 8x + number of red balloons = 12

Simplifying the equation, we get:

9x + number of red balloons = 12

Now, we can substitute the value of x into the equation to find the number of red balloons.

Substituting x into the equation

Since we don't have the exact value of x, we cannot determine the exact number of red balloons. However, we can still solve the equation in terms of x.

Let's assume x = 1. Substituting this value into the equation, we have:

9(1) + number of red balloons = 12

Simplifying, we get:

9 + number of red balloons = 12

Subtracting 9 from both sides, we find:

number of red balloons = 3

Therefore, if there is 1 blue balloon, 8 yellow balloons, and 3 red balloons, the total number of balloons will be 12.

Please note that this solution assumes the value of x is 1. If the value of x is different, the number of red balloons will also be different.

I hope this helps! Let me know if you have any further questions.
