Understanding Percentages: What Does 45 Represent of 135?

When you're gearing up for the Canadian Forces Aptitude Test (CFAT), trying to grasp mathematical concepts can feel like navigating a maze without a map. But don't sweat it! What if I told you that understanding percentages is as simple as pie? Let’s take a closer look at how to determine what percentage 45 represents of 135.

First things first, here’s the magic formula for calculating percentages:

[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

In our case, the "Part" is 45, and the "Whole" is 135. Now, roll up your sleeves because we’re about to plug these numbers into our formula. When we substitute in, it looks like this:

[ \text{Percentage} = \left( \frac{45}{135} \right) \times 100 ]

Before we hit 'calculate', let’s simplify that fraction first. Both the numerator (that's 45) and the denominator (yup, 135) can be divided by 45.

[ \frac{45}{135} = \frac{1}{3} ]

Now, what’s exciting about this is that a third of something translates beautifully into percentages. You probably guessed it—it's about 33.33%. When we multiply our fraction by 100, the simplicity shines through:

[ 0.3333 \times 100 = 33.33% ]

And if we want to keep things neat and tidy, we round that to 33%. There you go! 45 is 33% of 135!

Why Bother with Percentages in the CFAT?

You might be wondering, “Why do I even need to know this stuff?” Well, the CFAT isn’t purely about oral language or reasoning—it dips into math skills, too. Having a strong grasp of percentages can boost your confidence, not to mention your overall score. You know what? This knowledge extends beyond the CFAT into everyday scenarios. Whether you’re sharing a pizza with friends or calculating a sale, understanding percentages helps you make quick decisions.
