Whole Numbers..

<p>Hey guys, I was just going through Gruber's SAT guide, and on one of the problems, it talks about the apples different people in the problem have. Although my answer fit the problem, it says that you have to assume that each person has a whole number of apples. Is this always the case? Because, mathematically, there were multiple answers that would fit otherwise. Thanks!</p>

<p>This is a good question. There are situations where from context you are to assume that fractions are not permitted: number of children in a family is an example that comes to mind. Number of eggs a hen lays is another. Apples is potentially ambiguous: when you are picking apples, you pick whole #s...when you are eating them, nothing stops you from eating 2 and 1/2. So context is everything. But the SAT is usually written well enough that this won't be an issue as long as you are paying attention.</p>

<p>Ok. I just wasn't sure when to make the assumption. Thanks!</p>
