整数的 1/4 是多少?
表示和处理数字的方法称为数字系统。数字系统是一种表示数字的书写系统。它是用于通过使用数字或其他符号来表示给定集合的数字的数学符号。它允许我们进行算术运算,例如除法、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
让我们详细了解所有这些数字系统。
十进制数系统
十进制数字系统由十位数字组成,即从0到9。十进制数字系统的基数是10。这些数字可以用来表示或表达任何数值。
For example, the decimal number 153 consists of the digit 3 in ones place, the digit 5 in tens place and the digit 1 in hundreds place which can be represented as :
(1X102) + (5X101) + (3X100)
= (1X100) + (5X10) + (3) { where, 100 = 1}
= 100 + 50 + 3
= 153
二进制数制
二进制数系统仅由两位数字组成,即0和1。二进制数系统的基数是2。数字计算机以二进制数系统表示各种数据。
For example, convert 100112 into decimal number system.
(100111)2 = 1X25 + 0X24 + 0X23 + 1X22 + 1X21 + 1X20
= 32 + 0 + 0 + 4 + 2 + 1
= (39)10
八进制数系统
八进制数系统由 0 到 7 的数字组成。八进制数系统的基数是 8。八进制数系统基本上用于计算机应用程序。
For example, convert 1458 into decimal.
1458 = 1X82 + 4X81 + 5X80
= 64 + 32 + 5
= 10110
十六进制数系统
在十六进制数字系统中,数字首先从数字 0 到 9 表示为十进制数字系统,然后使用从 A 到 F 的字母表示数字。十六进制数字系统的基数是 16。
For example, convert 26BC16 to decimal.
26BC16 = 2X163 + 6X162 + 11X161 + 12X160
= 8192 + 1536 + 176 + 12
= 991610
什么是整数?
整数是没有分数的数字,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。所有的整数都是实数,但我们不能说所有的实数都是整数。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 1/4 是多少?
回答:
The number is 1/4 which can also be written as 0.25. Hence, the number 1/4 rounded off to the nearest whole number will be 0.
解释:
The whole numbers are numbers that start from zero.
Consider the number 1/4 as Y.
Y = 1/4
Dividing 1/4 to get the whole number,
so we get,
Y = 1/4
Y = 0.25
Now, rounding it off to the nearest whole number, we get, 0, because the digit after decimal is less than 5.
When the digit after the decimal is less than 5 then it is rounded off to the immediate lowest whole number,
and when the digit after decimal is more than or equal to 5, then it is rounded off to the immediate highest whole number.
Hence, 1/4 as a whole number will be 0.

问题 1. 22/5 是一个整数吗?
回答:
Given:- The number is 22/5
Explanation:
The whole numbers are numbers that start from zero.
Consider the number 22/5 as Y.
Y = 22/5
Dividing 22/5 to get the whole number,
so we get,
Y = 22/5
Y = 4.4
Rounding it off to the nearest whole number, we get, 4.
Therefore, the whole number of 22/5 is 4
问题 2. 145/4 是一个整数吗?
回答:
Given:- The number is 145/4
Explanation:
The whole numbers are numbers that start from zero.
Consider the number 145/4 as Y.
Y = 145/4
Dividing 145/4 to get the whole number,
so we get,
Y = 145/4
Y = 36.25
Rounding it off to the nearest whole number, we get, 36.
Therefore, the whole number of 145/4 is 36.
问题 3. 45/5 是一个整数吗?
回答:
Given:- The number is 45/5
Explanation:
The whole numbers are numbers that start from zero.
Consider the number 45/5 as Y.
Y = 45/5
Dividing 45/5 to get the whole number,
so we get,
Y = 45/5
Y = 9
Therefore, the whole number of 45/5 is 9.
