<p>Although you can grid in your answer as a fraction (in any form that fits in the grid), it is generally easier to just grid in the answer as a decimal - simply truncate the answer to fit.</p>
<p>For example, if your calculator gives a final answer of 2.379989999, you can simply grid in 2.37.</p>
<p>Note that you can also grid in the rounded decimal 2.38, but I prefer gridding the truncated decimal 2.37 since there is less to think about.</p>
<p>For all the information you need on gridding in, see my article “Overview of the Math Sections of the SAT.” It’s posted on CC - just do a search.</p>
