How is 'at most' understood in mathematics?

  1. Greater than or equal to

  2. Less than

  3. Less than or equal to

  4. Exactly equal to

The correct answer is: Less than or equal to

In mathematics, the phrase "at most" is interpreted to mean that a value or quantity can be less than or equal to a specified number. When we say something is "at most" a certain amount, we are setting an upper limit on that quantity. For example, if a problem states that there can be "at most 5 apples," it means that the number of apples can be any number from 0 to 5, inclusive. This reflects the idea of having a maximum limit while allowing for the possibility of being less than that limit as well. Therefore, the correct understanding of "at most" is captured by the concept of "less than or equal to," making that the accurate response.
