# What is 1/4th as a Whole Number?

The method to represent and work with numbers is known as the number system. A number system is a system of writing to represent numbers. It is the mathematical notation used to represent numbers of a given set by using digits or other symbols. It allows us to operate arithmetic operations such as division, multiplication, addition, subtraction.

Some important number systems are as follows:

- Decimal Number System
- Binary Number System
- Octal Number System
- Hexadecimal Number System

Let’s see about all these number systems in detail.

**Decimal Number System**

The decimal number system consists of ten digits i.e. from 0 to 9. The base of a decimal number system is 10. These digits can be used to represent or express any numeric value.

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 :

(1X10

^{2}) + (5X10^{1}) + (3X10^{0})= (1X100) + (5X10) + (3) { where, 10

^{0}= 1}= 100 + 50 + 3

= 153

**Binary Number System**

The binary number system consists of only two digits i.e. 0 and 1. The base of the binary number system is 2. The digital computer represents all kinds of data in a binary number system.

For example, convert 100112 into decimal number system.

(100111)

_{2}= 1X2^{5}+ 0X2^{4}+ 0X2^{3}+ 1X2^{2}+ 1X2^{1}+ 1X2^{0 }= 32 + 0 + 0 + 4 + 2 + 1

= (39)

**Octal Number System**

The octal number system consists of digits from 0 to 7. The base of an octal number system is 8. Octal number systems are basically used in computer applications.

For example, convert 145

_{8}into decimal.145

_{8}= 1X8^{2}+ 4X8^{1}+ 5X8^{0}= 64 + 32 + 5

= 101

**Hexadecimal Number System**

In the hexadecimal number system, numbers are first represented from digits 0 to 9 as decimal number system and then the numbers are represented using alphabets from A to F. The base of a hexadecimal number system is 16.

For example, convert 26BC

_{16}to decimal.26BC

_{16}= 2X16^{3}+ 6X16^{2}+ 11X16^{1}+ 12X16^{0}

^{ }= 8192 + 1536 + 176 + 12= 9916

### What are Whole Numbers?

The whole numbers are the numbers without fractions and are a collection of positive integers from 0 to infinity. All the whole numbers exist in number lines. All the whole numbers are real numbers but we can’t say that all the real numbers are whole numbers. Whole numbers cannot be negative. The whole numbers are represented by the symbol **“W”**. The examples are: 0, 23, 34, 45, 67, 867, 345, 56754, etc.

**What is 1/4th as a whole number?**

**Answer:**

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.

**Explanation:**

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.

### Similar Questions

**Question 1.** **What is 22/5 as a whole number?**

**Answer:**

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

**Question 2. What is 145/4 as a whole number?**

**Answer:**

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.

**Question 3. What is 45/5 as a whole number?**

**Answer:**

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.
