Explanation

To convert the binary number $11000111$to decimal:

1. Write down the binary number: $11000111$
   
2. Identify each bit's position from right to left: $2^0,2^1,2^2,2^3,2^4,2^5,2^6$
3. Assign the binary digits to their respective positions: $1<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}$
   

Now, calculate the decimal value:

$1\times 2^6+1\times 2^5+0\times 2^4+0\times 2^3+0\times 2^2+1\times 2^1+1\times 2^0$

$=64+32+0+0+0+2+1$

$=99$

So, the decimal value of $11000111$ is $99$

Therefore, the correct answer for the MCQ would be: $$99.
