1994 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 1994 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 1994, 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, 1994. 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 1994. 1994 - 1024 = 970.

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, 970. So, the next largest power of 2 is 29, which is less than or equal to 970. Now, we have to write 1 in the 29 place. And then subtract 512 from 970. 970 - 512 = 458. Continue this process using the next largest powers of 2 until you reach a remainder of 0. Fill in with 0s for any unused powers of 2.

Step 4 - Write the values in reverse order: We now write the numbers upside down to represent 1994 in binary. Therefore, 11111001010 is 1994 in binary.

Grouping Method: In this method, we divide the number 1994 by 2. Let us see the step-by-step conversion.

Step 1 - Divide the given number 1994 by 2. 1994 / 2 = 997. Here, 997 is the quotient, and 0 is the remainder.

Step 2 - Divide the previous quotient (997) by 2. 997 / 2 = 498. Here, the quotient is 498, and the remainder is 1.

Step 3 - Repeat the previous step. 498 / 2 = 249. Now, the quotient is 249, and 0 is the remainder. Continue this process until the quotient becomes 0.

Step 4 - Write down the remainders from bottom to top. Therefore, 1994 (decimal) = 11111001010 (binary).
