Introduction

In this article, we will delve into the world of mathematics and explore a real-life scenario involving time and fractions. Our protagonist, Leo, spent a significant amount of time working out at the gym, and we will use mathematical equations to determine the correct representation of his workout time.

The Problem

Leo spent the same amount of time working on each of 5 different weight machines and then spent $\frac{2}{3}$ of an hour on the treadmill. If he spent a total of $1 \frac{3}{4}$ hours at the gym, we need to find the correct equation that represents the total time spent at the gym.

Understanding the Time Spent on Weight Machines

Let's denote the time spent on each weight machine as $x$ . Since Leo spent the same amount of time on each machine, the total time spent on all 5 machines is $5x$ .

Understanding the Time Spent on the Treadmill

Leo spent $\frac{2}{3}$ of an hour on the treadmill. To convert this to a decimal, we can divide the numerator by the denominator: $\frac{2}{3} = 0.6667$ hours.

Understanding the Total Time Spent at the Gym

The total time spent at the gym is given as $1 \frac{3}{4}$ hours. To convert this to an improper fraction, we can multiply the whole number by the denominator and add the numerator: $1 \frac{3}{4} = \frac{7}{4}$ hours.

Setting Up the Equation

We can now set up an equation to represent the total time spent at the gym. The equation is:

5x + \frac{2}{3} = \frac{7}{4}

Solving the Equation

To solve for $x$ , we need to isolate the variable. We can start by subtracting $\frac{2}{3}$ from both sides of the equation:

5x = \frac{7}{4} - \frac{2}{3}

Finding a Common Denominator

To subtract the fractions, we need to find a common denominator. The least common multiple of 4 and 3 is 12. We can rewrite the fractions with a common denominator:

5x = \frac{21}{12} - \frac{8}{12}

Subtracting the Fractions

Now that the fractions have a common denominator, we can subtract them:

5x = \frac{13}{12}

Multiplying Both Sides by 12

To eliminate the fraction, we can multiply both sides of the equation by 12:

60x = 13

Dividing Both Sides by 60

Finally, we can solve for $x$ by dividing both sides of the equation by 60:

x = \frac{13}{60}

Conclusion

In this article, we used mathematical equations to determine the correct representation of Leo's workout time. We set up an equation to represent the total time spent at the gym and solved for the variable $x$ . The final answer is $\frac{13}{60}$ hours, which represents the time spent on each weight machine.
