Cracking the Code: Understanding Percentages with a Simple Example

Let’s face it: math can sometimes feel like an alien language. But what if I told you that it doesn’t have to be that way? Take a deep breath, and let's unravel the mystery of percentages together. Imagine this situation: you get a question that asks, "What is the result of 15% of 200?" You might think it’s a brain buster, but it’s simpler than you think!

The Question

Okay, so here’s the question that kicks off our little journey: What is 15% of 200? You’ve got four options to choose from:

• A. 25

• B. 30

• C. 20

• D. 15

Now let’s roll up our sleeves and dig into the math behind this question.

Finding the Answer

Here’s the thing—we need to multiply 200 by 0.15 to find out what 15% is. But before we dive into multiplication, let’s convert that pesky percentage into a decimal. You know what? It’s as easy as pie!

Here’s how it works:

1. Convert 15% into a decimal:

• 15% equals 15 divided by 100, which gives us 0.15.

2. Next, multiply:

• So, now we take 200 and multiply it by 0.15:

• 200 × 0.15 = 30.

Aha! There it is. The answer is 30—and that's option B, in case you were keeping score.

A Closer Look at Percentages

Now that we've cracked the code on this particular problem, let’s take a moment to chat about percentages. If you've ever been shopping and seen a "50% off" sign, you know how useful they can be. Understanding percentages isn’t just a math class necessity—it’s a life skill, and it can save you money! Imagine confidently strutting around stores, knowing exactly how much you’re saving. Sounds nice, right?

Percentages help us understand proportions, fractions, and even statistics better. They’re everywhere—whether we’re talking about discounts at your favorite store or calculating tips at a restaurant.
