如何将百分比更改为整数？

整数是包含在数字系统中的从 0 到无穷大的那些正整数。在数轴中，这些数字存在。结果，所有的数字都是真实的。我们可以断言所有整数都是实数，但事实并非如此。整数和负自然数组成整数集。结果，整数包括正数和负数，以及数字零。自然数、整数、整数和分数都是构成实数集的数字形式。

整数是完整的自然数集，包括“0”。 0、11、25、36、999、1200 等是一些实例。整数是包含零但不包含小数或小数部分的正整数（3/4、2.2 和 5.3 不是整数）。整数用符号 W 表示。W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,11,12,13,…}

如何将百分比更改为整数？

回答：

First we will discuss about percent,

Percent 

Percent or Percentage is a number that represents the hundredth part of any amount and is denoted by the percent sign %. A percent is also known as a ratio or fraction in which the total always equals 100. It is a dimensionless number, which means it lacks a unit of measurement.

Percentage simply implies one out of a hundred. The word “percent” has comes from the Latin phrase “per centum,” which implies that means “by a hundred”. Example: To convert the percentage into whole number, Remove the percent sign then Divide the numerator with 100 

• First case: 10% we can write as 10/100 in fraction or 0.10 in decimal form but decimal or fraction doesnot come in whole numbers .
• Second case: 200 % we can write it as 200/100 as simplified it 2, which is a whole number 

So it is clear that we can convert percent to whole number by dividing it 100 but it is not necessary that it will always give result in whole number.

Some Examples of percentage,  

• 20% of 300 is equal to (20/100) × 300 = 60
• 40% is equal to 40/100 = 4/10 = 2/5 
• 25% is equal to 25/100 = 1/4 …

示例问题

问题一：3.3%换算成小数会是什么结果？

解决方案：

Here given: 3.3%

First we will remove the percent symbol and then divide it by 100.

Therefore, 3.3% = 33/100 

= 0.33 

Hence, it is not a whole number.

问题2：找到整数225的30%？

解决方案：

Here 30% we can write as 30/100

Now 30% of 225

And multiply the whole number 225 by 30/100

= (30/100) × 225

By simplifying

= 67.5

Therefore the 30% of 225 is 67.5 

问题 3：将 300% 转换为整数？

解决方案：

Given: 300% 

To convert it into whole number 

First remove the percent sign and divide it by 100 

Therefore we can write 300% as 300/100

= 300/100

= 3 

Hence 3 is a whole number. 

问题 4：在商店，购买价值 4000 卢比的商品可享受 35% 的折扣。找到价值百分比？

解决方案：

Here the off is 35%

cost of product = 4000

Now to find 35% of 4000

We can write as 35% = 35/100

Now multiply the whole 4000 by 35/100

= 4000 × 35/100

By simplifying

=  40 × 35

= 1400

So there will be Rs 1400 off on purchase of worth Rs 4000

Therefore the percentage of 35% in value is Rs 1400 .

问题 5：找到 600 的 45%？

解决方案：

Here 45 % we can write as 45/100

Now 45% of 600

Multiply the number 600 by 45/100

= (45/100) × 600

By simplifying

= 45 × 6

Therefore the 45 % of 600 is 270

问题6：找到整数325的50%？

解决方案：

Here 50% we can write as 50/100

Now 50% of 325

And multiply the whole number 325 by 50/100

= (50/100) × 325

By simplifying

= 16250/100

Therefore the 50% of 325 is 162.5
