93 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 93 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. 2^0 = 1 2^1 = 2 2^2 = 4 2^3 = 8 2^4 = 16 2^5 = 32 2^6 = 64 2^7 = 128 Since 128 is greater than 93, we stop at 2^6 = 64.

Step 2 - Identify the largest power of 2: In the previous step, we stopped at 2^6 = 64. 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, 93. Since 2^6 is the number we are looking for, write 1 in the 2^6 place. Now the value of 2^6, which is 64, is subtracted from 93. 93 - 64 = 29.

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, 29. So, the next largest power of 2 is 2^4, which is less than or equal to 29. Now, we have to write 1 in the 2^4 place. And then subtract 16 from 29. 29 - 16 = 13.

Step 4 - Continue the process: Find the next largest power of 2 for the remainder, 13. The largest power is 2^3 = 8. Write 1 in the 2^3 place. Subtract 8 from 13. 13 - 8 = 5.

Step 5 - Continue the process: Find the next largest power of 2 for the remainder, 5. The largest power is 2^2 = 4. Write 1 in the 2^2 place. Subtract 4 from 5. 5 - 4 = 1.

Step 6 - Finalize the powers: The largest power of 2 for 1 is 2^0 = 1. Write 1 in the 2^0 place. Subtract 1 from 1. 1 - 1 = 0. We need to stop the process here since the remainder is 0.

Step 7 - Identify the unused place values: In step 2, 3, 4, 5, and 6, we wrote 1 in the 2^6, 2^4, 2^3, 2^2, and 2^0 places. Now, we can just write 0s in the remaining places, which are 2^5 and 2^1. Now, by substituting the values, we get, 1 in the 2^0 place 0 in the 2^1 place 1 in the 2^2 place 1 in the 2^3 place 1 in the 2^4 place 0 in the 2^5 place 1 in the 2^6 place

Step 8 - Write the values in reverse order: We now write the numbers upside down to represent 93 in binary. Therefore, 1011101 is 93 in binary.

Grouping Method: In this method, we divide the number 93 by 2. Let us see the step-by-step conversion.

Step 1 - Divide the given number 93 by 2. 93 / 2 = 46. Here, 46 is the quotient and 1 is the remainder.

Step 2 - Divide the previous quotient (46) by 2. 46 / 2 = 23. Here, the quotient is 23 and the remainder is 0.

Step 3 - Repeat the previous step. 23 / 2 = 11. Now, the quotient is 11, and 1 is the remainder.

Step 4 - Repeat the previous step. 11 / 2 = 5. Here, the quotient is 5, and 1 is the remainder.

Step 5 - Repeat the previous step. 5 / 2 = 2. Here, the quotient is 2, and 1 is the remainder.

Step 6 - Repeat the previous step. 2 / 2 = 1. Here, the quotient is 1, and 0 is the remainder.

Step 7 - Repeat the previous step. 1 / 2 = 0. Here, the remainder is 1. And we stop the division here because the quotient is 0.

Step 8 - Write down the remainders from bottom to top. Therefore, 93 (decimal) = 1011101 (binary).
