Which of the following decimal can be most accurately shown in binary?

.1 .2 .3
.4 .5 .6
.7 .8 .9

This was a question one of my friends received in exit exams.

In binary, decimal places are shown as:
2^-1, 2^-2, etc, so you get 1/2, 1/4, 1/16, etc.

To answer your question: 0.5

Yup, I wasn't sure and had guessed wrong when they asked me.
