Quick Grid-In Question

<p>I was taking a pracitce test the other day and one of the answers on the grid-in was 6.55555...(continues on). Remembering from what the PR book said, I can either grid it in as 6.555 or I can round it 6.6. So I rounded it to 6.6 and it turned out to be wrong.</p>

<p>So just a quick clarification, putting the actual answer with repeating decimals is the only correct way right?</p>

<p>You can either truncate or round. But you have to use all 4 blocks. The correct answer for that problem could have been 6.555 truncated or 6.556 rounded.</p>

<p>ok thank you. never knew you had to use all the blocks.</p>
