Convert each decimal number to its binary equivalent 511

To convert the decimal number \(511\) to its binary equivalent, follow these steps:

1. **Find the highest power of 2** less than or equal to 511. The highest power is \(2^8 = 256\).
2. **Subtract this value** from 511:
   \[
   511 - 256 = 255
   \]
3. **Repeat the process** for the remainder (255) using the next lower powers of 2:
   - \(2^7 = 128\): 
     \[
     255 - 128 = 127
     \]
   - \(2^6 = 64\): 
     \[
     127 - 64 = 63
     \]
   - \(2^5 = 32\): 
     \[
     63 - 32 = 31
     \]
   - \(2^4 = 16\): 
     \[
     31 - 16 = 15
     \]
   - \(2^3 = 8\): 
     \[
     15 - 8 = 7
     \]
   - \(2^2 = 4\): 
     \[
     7 - 4 = 3
     \]
   - \(2^1 = 2\): 
     \[
     3 - 2 = 1
     \]
   - \(2^0 = 1\): 
     \[
     1 - 1 = 0
     \]

4. **Write the binary equivalent** by placing a `1` in the positions corresponding to the powers of 2 that were subtracted, and `0` in all other positions. Since all powers from \(2^8\) down to \(2^0\) were used, the binary representation is:

\[
\text{Binary equivalent of } 511 = 111111111_2
\]
