2010 in binary is written as 11111011010 because the binary system uses only two digits, 0 and 1, to represent numbers. This number system is used widely in computer systems. In this topic, we are going to learn about the binary representation of 2010.
The process of converting 2010 from decimal to binary involves dividing the number 2010 by 2. Here, it is getting divided by 2 because the binary number system uses only 2 digits (0 and 1). The quotient becomes the dividend in the next step, and the process continues until the quotient becomes 0.
This is a commonly used method to convert 2010 to binary. In the last step, the remainder is noted down bottom side up, and that becomes the converted value.
For example, the remainders noted down after dividing 2010 by 2 until getting 0 as the quotient is 11111011010. Remember, the remainders here have been written upside down.
In the table shown below, the first column shows the binary digits (1 and 0) for 2010.
The second column represents the place values of each digit, and the third column is the value calculation, where the binary digits are multiplied by their corresponding place values.
The results of the third column can be added to cross-check if 11111011010 in binary is indeed 2010 in the decimal number system.
2010 can be converted easily from decimal to binary. The methods mentioned below will help us convert the number. Let’s see how it is done.
Expansion Method: Let us see the step-by-step process of converting 2010 using the expansion method.
Step 1 - Figure out the place values: In the binary system, each place value is a power of 2. Therefore, in the first step, we will ascertain the powers of 2.
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64
27 = 128
28 = 256
29 = 512
210 = 1024
211 = 2048 Since 2048 is greater than 2010, we stop at 2^10 = 1024.
Step 2 - Identify the largest power of 2: In the previous step, we stopped at 210 = 1024. This is because in this step, we have to identify the largest power of 2, which is less than or equal to the given number, 2010. Since 210 is the number we are looking for, write 1 in the 210 place. Now the value of 210, which is 1024, is subtracted from 2010. 2010 - 1024 = 986.
Step 3 - Identify the next largest power of 2: In this step, we need to find the largest power of 2 that fits into the result of the previous step, 986. So, the next largest power of 2 is 29, which is equal to 512. Now, we have to write 1 in the 29 places. And then subtract 512 from 986. 986 - 512 = 474.
Step 4 - Continue the process: We continue this method, identifying the next largest powers of 2 and subtracting their values until the remainder is 0. The powers of 2 used will have a 1 placed in their positions; all others will have a 0. Using this method, the binary representation of 2010 is 11111011010.
Grouping Method: In this method, we divide the number 2010 by 2. Let us see the step-by-step conversion.
Step 1 - Divide the given number 2010 by 2. 2010 / 2 = 1005. Here, 1005 is the quotient, and 0 is the remainder.
Step 2 - Divide the previous quotient (1005) by 2. 1005 / 2 = 502. Here, the quotient is 502, and the remainder is 1.
Step 3 - Repeat the previous step. 502 / 2 = 251. Now, the quotient is 251, and 0 is the remainder.
Step 4 - Continue the division process until the quotient is 0.
Step 5 - Write down the remainders from bottom to top. Therefore, 2010 (decimal) = 11111011010 (binary).
There are certain rules to follow when converting any number to binary. Some of them are mentioned below:
This is one of the most commonly used rules to convert any number to binary. The place value method is the same as the expansion method, where we need to find the largest power of 2. Let’s see a brief step-by-step explanation to understand the first rule. Find the largest power of 2 less than or equal to 2010. Since the answer is 210, write 1 next to this power of 2. Subtract the value (1024) from 2010. So, 2010 - 1024 = 986. Find the largest power of 2 less than or equal to 986. The answer is 29. So, write 1 next to this power. Continue this method until the remainder is 0, using 0s for unused powers. The final conversion will be 11111011010.
The division by 2 method is the same as the grouping method. A brief step-by-step explanation is given below for better understanding. First, 2010 is divided by 2 to get 1005 as the quotient and 0 as the remainder. Now, 1005 is divided by 2. Here, we will get 502 as the quotient and 1 as the remainder. Continue dividing the quotient by 2 until the quotient becomes 0. Now, we write the remainders upside down to get the binary equivalent of 2010, 11111011010.
This rule also involves breaking the number into powers of 2. Identify the powers of 2 and write it down in decreasing order, i.e., 210, 29, 28, and so on. Find the largest power that fits into 2010. Repeat the process and allocate 1s and 0s to the suitable powers of 2. Combine the digits (0 and 1) to get the binary result.
The limitation of the binary system is that only 0s and 1s can be used to represent numbers. The system doesn’t use any other digits other than 0 and 1. This is a base 2 number system, where the binary places represent powers of 2. So, every digit is either a 0 or a 1. To convert 2010, we use the appropriate 1s and 0s for different powers of 2.
Learning a few tips and tricks is a great way to solve any mathematical problems easily. Let us take a look at some tips and tricks for binary numbers up to 2010.
Memorize to speed up conversions: We can memorize the binary forms for smaller numbers to quickly build up to larger numbers.
Recognize the patterns: There is a peculiar pattern when converting numbers from decimal to binary. For example, the binary representation of consecutive numbers often follows a recognizable pattern.
Even and odd rule: Whenever a number is even, its binary form will end in 0. For example, 2010 is even, and its binary form is 11111011010. Here, the binary of 2010 ends in 0. If the number is odd, then its binary equivalent will end in 1.
Cross-verify the answers: Once the conversion is done, we can cross-verify the answers by converting the number back to the decimal form. This will eliminate any unforeseen errors in conversion.
Practice by using tables: Writing the decimal numbers and their binary equivalents on a table will help us remember the conversions.
Here, let us take a look at some of the most commonly made mistakes while converting numbers to binary.
Convert 2010 from decimal to binary using the place value method.
11111011010
210 is the largest power of 2, which is less than or equal to 2010.
So place 1 next to 210.
Subtracting 1024 from 2010, we get 986.
So the next largest power would be 29. Place another 1 next to 29.
Continue this method until the remainder is 0, placing 0s in unused powers of 2.
By using this method, we find the binary form of 2010.
Convert 2010 from decimal to binary using the division by 2 method.
11111011010
Divide 2010 by 2.
In the next step, the quotient becomes the new dividend.
Continue the process until the quotient becomes 0.
Now, write the remainders upside down to get the final result.
Convert 2010 to binary using the representation method.
11111011010
Break the number 2010 into powers of 2 and find the largest powers of 2.
We get 210. So 1 is placed next to 210.
Next, 2010 - 1024 = 986.
Now, the largest power of 2 is 29.
Once again, 1 is placed next to 29.
Continue this method, and after getting 0, fill in with zeros for unused powers of 2.
By following this method, we get the binary value of 2010 as 11111011010.
How is 2010 written in decimal, octal, and binary form?
Decimal form - 2010 Octal - 3732 Binary - 11111011010
The decimal system is also called the base 10 system.
In this system, 2010 is written as 2010 only.
We have already seen how 2010 is written as 11111011010 in binary.
So, let us focus on the octal system, which is base 8.
To convert 2010 to octal, we need to divide 2010 by 8.
So, 2010 / 8 = 251 with 2 as the remainder.
In the next step, divide 251 by 8 to get 31 with 3 as the remainder, then 31 by 8 to get 3 with 7 as the remainder, and finally 3 by 8 to get 0 with 3 as the remainder.
The octal equivalent of 2010 is 3732.
Express 2010 - 5 in binary.
11111011001
2010 - 5 = 2005.
So, we need to write 2005 in binary.
Start by dividing 2005 by 2.
We get 1002 as the quotient and 1 as the remainder.
Continue dividing the quotient by 2 until it becomes 0.
Now write the remainders from bottom to top to get 11111011001 (binary of 2005).
