Question

Quizplus · Accepted Answer

To convert a binary number to hexadecimal, we group the bits into groups of four starting from the rightmost bit. If necessary, we add leading zeros to the leftmost group to make sure it has four bits.

In this case, we have $1\ 1111$. We add a leading zero to get $0001\ 1111$. Now we group the bits into groups of four: $0001\ 1111 = 	extrm{1F}_{16}$. Therefore, the correct answer is $\boxed{	extbf{(C)}}$.
