2025 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 2025 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 ... 210 = 1024 211 = 2048

Since 2048 is greater than 2025, we stop at 210 = 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, 2025. 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 2025. 2025 - 1024 = 1001.

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, 1001. So, the next largest power of 2 is 29 = 512. Now, we have to write 1 in the 29 place. And then subtract 512 from 1001. 1001 - 512 = 489.

Step 4 - Continue the process: Repeat this process to find the next powers of 2 that fit into the result and subtract until you reach 0, writing 1s and 0s as needed. 489 - 256 = 233 (28 = 256) 233 - 128 = 105 (27 = 128) 105 - 64 = 41 (26 = 64) 41 - 32 = 9 (25 = 32) 9 - 8 = 1 (23 = 8) 1 - 1 = 0 (20 = 1) Now, by substituting the values, we get, 1 in the 210 place 1 in the 29 place 1 in the 28 place 1 in the 27 place 1 in the 2^6 place 1 in the 25 place 0 in the 24 place 0 in the 23 place 1 in the 22 place 0 in the 21 place 1 in the 20 place

Step 5 - Write the values in reverse order: We now write the numbers upside down to represent 2025 in binary. Therefore, 11111100101 is 2025 in binary.

Grouping Method: In this method, we divide the number 2025 by 2. Let us see the step-by-step conversion.

Step 1 - Divide the given number 2025 by 2. 2025 / 2 = 1012. Here, 1012 is the quotient and 1 is the remainder.

Step 2 - Divide the previous quotient (1012) by 2. 1012 / 2 = 506. Here, the quotient is 506 and the remainder is 0.

Step 3 - Repeat the previous step. 506 / 2 = 253. Now, the quotient is 253, and 0 is the remainder.

Step 4 - Repeat the previous step. 253 / 2 = 126. Here, the remainder is 1. Continue this process until the quotient becomes 0. Finally, write down the remainders from bottom to top. Therefore, 2025 (decimal) = 11111100101 (binary).
