Mastering Workkeys Math: Understanding Total Hours with Real Examples

How many total hours did a contractor work if he reported hours of 4 1/4, 3 1/4, 7 1/4, and 5 1/4 over four days?

• A. 19.00 hours
• B. 19.25 hours
• C. 20.00 hours
• D. 20.25 hours

Answer: (C)

To find the total hours worked by the contractor, you need to add all the hours reported over the four days. Each of the reported times is given in a mixed number format. First, let's convert each mixed number into an improper fraction or a decimal for easier addition. The mixed number 4 1/4 can be expressed as 4.25 in decimal form, 3 1/4 is 3.25, 7 1/4 is 7.25, and 5 1/4 is 5.25. Now, add these numbers together: 4.25 + 3.25 + 7.25 + 5.25 Calculating this step by step: 1. Adding the first two: 4.25 + 3.25 = 7.50 2. Adding the next: 7.50 + 7.25 = 14.75 3. Finally, adding the last one: 14.75 + 5.25 = 20.00 Now, the total hours worked amounts to 20.00 hours. This indicates that the addition of the mixed numbers was carefully done, arriving at a total

When it comes to tackling the Workkeys Math Test, you might find yourself wondering just how to add those quirky mixed numbers we see in real-world scenarios. Don't sweat it! We are diving into how to find total hours worked by a contractor using simple math. Understanding this not only sharpens your math skills but also shows how numbers translate into real statements—like hours worked!

The Basics: What’s a Mixed Number?

You know what? Mixed numbers can seem a bit tricky at first glance, but once you get the hang of 'em, they’re super useful! A mixed number is just a whole number plus a fraction. Think of it like pizza slices—if you eat 3 whole pizzas and a quarter of another, you've got a mixed number: 3 1/4!

Breaking it Down: Our Contractor's Hours

Let’s take a close look at a contractor who reported hours worked over four days as follows:

• 4 1/4 hours

• 3 1/4 hours

• 7 1/4 hours

• 5 1/4 hours

First, let’s convert those mixed numbers into decimal form. Why? Because it makes adding them up a whole lot easier. Here’s how it goes:

• 4 1/4 hours = 4 + 0.25 = 4.25 hours

• 3 1/4 hours = 3 + 0.25 = 3.25 hours

• 7 1/4 hours = 7 + 0.25 = 7.25 hours

• 5 1/4 hours = 5 + 0.25 = 5.25 hours

When you look at those decimals, it’s a bit like turning a puzzle into a straightforward picture.

Add ’Em Up: The Total Calculation

Now the fun part—adding those hours together! Let’s break it down step by step.

1. Start with the first pair:

4.25 + 3.25 = 7.50

2. Add the next number:

7.50 + 7.25 = 14.75

3. Now, let’s add the final hours:

14.75 + 5.25 = 20.00

And just like that, we see the total hours worked is 20.00 hours! But hold on—our calculations prompted a little confusion. The original question had suggested an answer of 19.25 hours, leading us to personally understand how important careful addition is in real-life applications and tests alike.

Why Does This Matter?

You see, being able to add mixed numbers quickly and correctly is more than just a skill for the Workkeys Test- it’s a fundamental building block for everything from budgeting your time to calculating expenses in everyday life. Think about it! Whether you’re managing a project or just tracking your own hours, math plays a pivotal role.

So, as you gear up for the Workkeys Math Test, remember this little exercise. Don’t just memorize how to convert and add, practice it too! The more you engage with these concepts, the more confident you’ll feel when facing real-life math challenges.

Final Thoughts

Here’s the thing: mastering topics like these opens doors—be it in your career or personal life. You never know when the correct application of math will come in handy, whether you’re figuring out contractor hours or simply working out how long that Netflix binge really lasted. So keep at it and see math as a friend rather than a foe. Happy studying!
