20.16 和 3.17 之间有多少个整数？
表示和处理数字的方法被理解为记数系统或数字系统。数字系统可以是表示数字的书写系统。它是使用数字或其他符号表示给定集合的数字的符号。它允许我们进行算术运算，如除法、乘法、加法、减法。
一些重要的数字系统如下：
- 十进制数系统
- 二进制数制
- 八进制数系统
- 十六进制数系统
什么是整数？
整数是没有分数、小数的数字，是从 0 到无穷大的正整数的集合。所有整数都存在于数轴中。所有整数都是实数，但我们不会说每个重要的数字都是整数。整数不能为负数。整数用符号“W”表示。示例为：0、23、34、45、67、867、345、56754 等。
整数的性质
整数的性质有助于我们更好地了解数字。此外，它们在某些操作下创建计算，例如非常简单的加法、减法、乘法和除法。整数的不同性质如下：
- 加法和乘法的闭包。
- 加法和乘法的交换性质。
- 加法和乘法的关联属性。
- 乘法对加法的分配性质。
- 加法和乘法的标识。
在数字之间查找整数的步骤：
以下是在不包括这些数字的数字之间查找整数的步骤：
第1步：减去数字。
第 2 步：从结果中减去 1。
For Example: Whole numbers between 10 and 5 are 10-5-1 = 4 i.e. 6, 7, 8, and 9
20.16 和 3.17 之间有多少个整数？
Since whole numbers do not include fractions and decimal values, 20.16 and 3.17 will not be considered as whole numbers. But, it can be rounded off to the nearest whole number possible.
Therefore the nearest whole number for 20.16 will be 20 and for 3.17 it will be 3, because if the digit after the decimal is less than or equal to 5, the decimal is rounded up to the next whole number.
Now, we have to find the whole numbers between 20 and 3.
- Subtract the numbers
- Subtract 1 from the obtained result.
Therefore, 20 – 3 = 17 and 17 – 1 = 16
Therefore, there are 16 whole numbers between 20 and 3 which are 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19.
示例问题
问题 1. 15 到 7 之间有多少个整数？
回答：
Here given two numbers 15 and 7.
- Subtract the numbers
- Subtract 1 from the obtained result.
15 – 7 = 8
8 – 1 = 7
Therefore, there are 7 whole numbers between 15 and 7 are 8, 9, 10, 11, 12, 13, 14.
问题 2. 4.58 和 13.7 之间有多少个整数？
回答：
Since whole numbers do not include fractions and decimal values, 4.58 and 13.7 will not be considered as whole numbers. But, it can be rounded off to the nearest whole number possible.
Therefore the nearest whole number for 4.58 will be 5 and for 13.7 it will be 14, because if the digit after decimal is greater than or equal to 5, the decimal is rounded up to the next whole number.
Now, we have to find the whole numbers between 14 and 5.
- Subtract the numbers
- Subtract 1 from the obtained result.
14 – 5 = 9
9 – 1 = 8
Therefore, there are 8 whole numbers between 14 and 5 which are 6, 7, 8, 9, 10, 11, 12, 13.
问题 3. 45 到 61 之间有多少个整数？
回答：
Here given two numbers 45 and 61.
- Subtract the numbers
- Subtract 1 from the obtained result.
61 – 45 = 16
16 – 1 = 15
Therefore, there are 15 whole numbers between 45 and 61 which are 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56,57, 58, 59, 60.
