当您有股息但没有设计者时，如何计算百分比（或平均值）？

6 个解决方案

You have a lot of values, and some of them figure into your average - or percentage - and some of them probably don't. 您有很多值，其中一些值会计入平均值或百分比，而其中一些可能没有。 You are not expressing the problem clearly enough for anyone to be able to give you a meaningful answer. 您没有足够清楚地表达问题，任何人都无法给您有意义的答案。

A percentage represents a fraction, one value divided by another (multiplied by 100 to express it in percentage, but that's trivial and not part of the problem). 百分比代表分数，一个值除以另一个值（乘以100即可表示为百分比，但这是微不足道的，而不是问题的一部分）。 What is the value that represents 100%? 代表100％的值是多少？ And what value are you trying to assign? 您要分配什么价值？ In what way do you think that the quantity of bonuses should affect the percentage? 您认为奖金数量应以哪种方式影响百分比？

Some possible answers: 一些可能的答案：

The total bonus earned by an individual, as compared to her nominal salary. 个人获得的总奖金，与其名义工资相比。 If she earns $50k and her bonus is $20K, that is 20/50 *100 = 40%. 如果她的收入为$ 50k，奖金为$ 20K，则20/50 * 100 = 40％。

The total bonus earned by an individual, as compared to all the bonuses given out that year. 个人获得的总奖金，与当年发出的所有奖金相比。 If she received the same $20K, but the company gave out $100K in bonuses, then the percentage is 20/100 * 100 = 20%. 如果她获得了相同的$ 20K，但公司发放了$ 100K奖金，则该百分比为20/100 * 100 = 20％。

The most recent bonus earned by an individual, as compared to all bonuses awarded to her this year. 个人获得的最新奖金，与今年授予她的所有奖金相比。 If she got $5K for her last bonus, and the total was $20, that's 5/20 * 100 = 25%. 如果她最后一次获得$ 5K奖金，而总奖金为$ 20，则5/20 * 100 = 25％。

We really don't have enough information to go on; 我们确实没有足够的信息可以继续下去。 it could be any of these, or something entirely different. 可能是这些中的任何一个，或者是完全不同的东西。 It is entirely possible to have a percentage value greater than 100%. 百分比值完全有可能大于100％。

You need to be more specific or give an example. 您需要更具体或举一个例子。 But I will give an answer based off of what I THINK you mean. 但是，我将根据您的意思给出答案。

You cannot find the average of one lone number. 您找不到一个单独数字的平均值。 If you were saying a temperature of 125 degrees every hour you could do it, The answer would obviously be 125. It is the closest thing that I can think of to what you are asking. 如果您每小时说的温度是125度，那么答案显然是125。这是我能想到的最接近您要求的内容。 You need to be more specific or the problem cannot be done. 您需要更具体，否则问题就无法解决。 Otherwise use the simple formula: Sum/Number of integers. 否则，请使用简单的公式：Sum /整数数。 Also known as the mean. 也称为均值。 So that would be 125/1, which is still 125. 这样就等于125/1，仍然是125。

The average of one value is that value (Total number=1). 一个值的平均值就是那个值（总数= 1）。

But this probably means I don't understand your question. 但这可能意味着我不理解您的问题。

Without knowing the number of years, you need to know something else about the range of bonuses possible. 在不知道年数的情况下，您需要了解其他可能的奖金范围。 ie does it have to be a whole number between 15 - 25%. 也就是说，它必须是15-25％之间的整数。 However, this is largely guessing. 但是，这在很大程度上是猜测。

To get an average, you need a total and a count. 要获得平均值，您需要总计和计数。 BTW: In your case you want the geometric average, but you need to know the same things. 顺便说一句：在您的情况下，您需要几何平均值，但您需要了解相同的知识。

如果您输入的是一个数字列表，则显示百分比值意味着您需要计算总计，然后查看每个总计有多少：例如，如果您有110、110、110，则总计330，每个值将显示为110/330 = 0.33 =总数的33％。

In addition, if I have three decimal values 120, 4420, and 230. How can I get a number less than 1 that represent the average of these 3 values? 另外，如果我有三个十进制值120、4420和230。如何获得小于1的数字来表示这三个值的平均值？

You cannot. 你不能。 The average of those 3 numbers will be (120 + 4420 + 230) / 3. That will never be less than one. 这3个数字的平均值将为（120 + 4420 + 230）/3。永远不会小于1。 Maybe you are confused about what average means? 也许您对平均值的含义感到困惑？
