Introduction

Melanie, an avid angler, spent her day fishing and was thrilled to catch four fish. Each of these fish weighed a fraction of a pound, specifically $\frac{1}{3}$ of a pound. In this article, we will delve into the world of mathematics to calculate the total weight of all the fish Melanie caught.

Understanding the Problem

To find the total weight of the fish, we need to multiply the weight of each fish by the number of fish caught. Since each fish weighs $\frac{1}{3}$ of a pound, we can represent this as a fraction. The number of fish caught is 4, which can be represented as a whole number.

Calculating the Total Weight

To calculate the total weight of the fish, we multiply the weight of each fish by the number of fish caught. This can be represented mathematically as:

Total Weight = Weight of each fish × Number of fish

Substituting the values, we get:

Total Weight = $\frac{1}{3}$ × 4

To multiply a fraction by a whole number, we multiply the numerator (1) by the whole number (4) and keep the denominator (3) the same:

Total Weight = $\frac{1 × 4}{3}$

Total Weight = $\frac{4}{3}$

Simplifying the Fraction

The fraction $\frac{4}{3}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 1. However, we can express this fraction in decimal form to make it easier to understand:

$\frac{4}{3}$ = 1.33

Conclusion

In conclusion, Melanie's four fish weighed a total of 1.33 pounds. This calculation demonstrates the importance of understanding fractions and how to apply mathematical operations to solve real-world problems.
