Understanding the Phrase: "9 Less Than the Number of Volunteers Last Month"

The phrase "9 less than the number of volunteers last month" can be represented as what?

• A. v + 9
• B. v - 9
• C. 9 - v
• D. v/9

Answer: (B)

The phrase "9 less than the number of volunteers last month" describes a mathematical operation where you take the total number of volunteers, represented by 'v', and subtract 9 from it. In this expression, "less than" indicates that the number of volunteers is being reduced by 9. Thus, you start with the value of 'v' and perform the operation of subtraction. This aligns directly with the expression 'v - 9,' which effectively captures the original phrase. The other options do not appropriately represent the phrase as they either add 9 or manipulate the number in a way that does not reflect the instruction to decrease by 9. Therefore, 'v - 9' is the accurate representation of the original statement.

When tackling math problems, especially those involving phrases, it’s crucial to translate the verbal cue into mathematical expressions correctly. Take, for instance, the phrase “9 less than the number of volunteers last month.” Sounds familiar? It really encapsulates a simple mathematical operation where we take a number and reduce it—specifically, subtracting 9.

So, let’s break it down step by step. We represent the total number of volunteers from the previous month with the letter ‘v’. This variable isn’t just some abstract concept; it holds the key to unlocking all kinds of useful information. Now, since we’re focusing on the phrase, “9 less than,” here's what happens: we need to reduce our ‘v’ by 9. So, naturally, the correct expression to represent this operation is v - 9.

Now, you might be wondering, “What happens to the other options available?” Well, let's address them for a moment. We’ve got A (v + 9), which would imply that we’re adding 9 to the number of volunteers—definitely not what we want. Then there's C (9 - v), which distorts the relationship entirely by flipping it around and subtracting the number of volunteers from 9—also not applicable. Lastly, option D (v/9) would tell us to divide the figure, which doesn’t reflect our original phrase either.

By now, you might be thinking about how similar phrases could lead to different mathematical formulations. That’s key! Sometimes, a tiny change in wording can significantly alter the intended operation. This highlights why precise language matters in math—your mathematical success hinges on understanding these subtleties.

In conclusion, getting familiar with phrases and how to translate them into numbers is a fundamental skill, especially handy if you're gearing up for assessments like the Kaplan Nursing Entrance Exam. And believe me, honing these skills can save you heaps of time and frustration down the line. Remember, “9 less than the number of volunteers last month” = v - 9—simple but powerful, right? So next time you come across a similar phrase, you’ll feel ready to tackle it without breaking a sweat.
