如何找到整数的 1%?
整数被定义为数字系统的子集,它由包括 0 在内的所有正整数组成。数字从零计数到正无穷大。整数主要用于计数、基本量的测量和日常计算。正数包括零,从 0 计数到无穷大。这些数字不包括分数或小数。整数用“W”表示。
整数 (W) 示例 = 0、1、2、3、4、5,6…
包括零在内的自然数的唯一组成部分是整数。整数的子集由 {0, 1, 2, 3, 4, 5, 6, 7…….} 给出,整数的集合不包括分数、小数和负整数。
因此,整数的标准形式是 0, 1, 2, 3, 4, 6, 8, 90,...
百分比
“百分比”一词源自拉丁语“per centum”,意思是“按百”。一个可以表示为 100 的分数的数字或比率,要计算此百分比,请将该数字除以整数并乘以 100。
百分比表示每百个中的给定部分或数量。百分比是以100为分母的分数。它用符号“ % ”表示。
如何找到整数的百分之一?
回答:
Percentage itself means a part per hundred. The word percent called percent per 100. It is denoted by %. Percent can be represented in decimal as well as fraction.
Formulae to calculate the Percentage = (Value/Total Value)×100
Examples:
- 20% of 200 is equal to (20/100) × 200 = 40
- 30% is equal to 30/100 = 3/10
- 70% is equal to 70/100 = 7/10 ……
To find one percent of whole number
Example 1: Find the 1% percent of 50?
Solution: 1% of 50 is equal to 1/100 × 50
= 50/100
= 1/2
Therefore 1% of 50 is 1/2
Example 2: Find the 1% of 1000?
Solution: 1 % of 1000 is equal to {1/100 × 1000}
= 1000/100
= 10
示例问题
问题 1:找到 100 的 20%?
解决方案:
Here 20% we can write as 20/100
Now 20% of 100
and multiply the whole number 100 by 20/100
= (20/100) × 100
By simplifying
= 20
therefore the 20% of 100 is 20
问题 2:在商店,购买价值 5000 卢比的商品可享受 30% 的折扣。找到价值百分比?
解决方案:
Here the off is 30%
cost of product = 5000
Now to find 30% of 5000
We can write as 30% = 30/100
Now multiply the whole 5000 by 30/100
= 5000 × 30/100
By simplifying
= 50 × 30
= 1500
So there will be Rs 1500 off on purchase of worth Rs 5000
therefore the percentage of 30% in value is 1500
问题 3:找到 500 的 25%?
解决方案:
Here 25 % we can write as 25/100
Now 25% of 500
and multiply the whole number 500 by 25/100
= (25/100) × 500
By simplifying
= 125
therefore the 25 % of 500 is 125
问题 4:如果山姆在他的数学考试中得了 30 分,找出他在数学中的百分比?
解决方案:
Total marks = 100
Sam scored = 30
now percentage (%) = (marks gained /Total Marks) × 100
= 30/100 × 100
= 30%
问题 5:找到 500 的 35%?
解决方案:
Here 35 % we can write as 35/100
Now 35% of 500
Multiply the number 500 by 35/100
= (35/100) × 500
By simplifying
= 175
Therefore the 35 % of 500 is 175
