Introduction

In this article, we will explore the concept of calculating the total weight of two backpacks, each belonging to a different boy. We will use the given weights of the backpacks, which are in mixed fractions, to find the total weight. This problem requires an understanding of fractions and basic arithmetic operations.

Understanding the Weights of the Backpacks

The weight of John's backpack is given as $$5 \frac{1}{2}$$ pounds, and the weight of Tyrone's backpack is given as $$6 \frac{1}{2}$$ pounds. To calculate the total weight, we need to add these two weights together.

Converting Mixed Fractions to Improper Fractions

Before we can add the weights, we need to convert the mixed fractions to improper fractions. An improper fraction is a fraction where the numerator is greater than or equal to the denominator.

To convert a mixed fraction to an improper fraction, we multiply the whole number part by the denominator and add the numerator. We then write the result as the new numerator, with the same denominator.

For John's backpack, we have:

5 \frac{1}{2} = \frac{(5 \times 2) + 1}{2} = \frac{10 + 1}{2} = \frac{11}{2}

For Tyrone's backpack, we have:

6 \frac{1}{2} = \frac{(6 \times 2) + 1}{2} = \frac{12 + 1}{2} = \frac{13}{2}

Adding the Weights

Now that we have converted the mixed fractions to improper fractions, we can add the weights together.

\frac{11}{2} + \frac{13}{2} = \frac{11 + 13}{2} = \frac{24}{2} = 12

Conclusion

The total weight of both boys' backpacks is 12 pounds. This problem required an understanding of fractions and basic arithmetic operations. We converted the mixed fractions to improper fractions and then added the weights together to find the total weight.
