Introduction

In this problem, we are given that Mark has a certain amount of rope and gives a fraction of it to his friend. We need to calculate the amount of rope Mark gave to his friend. This problem involves basic arithmetic operations and fractions.

Calculating the Amount of Rope Given

To find the amount of rope Mark gave to his friend, we need to multiply the total amount of rope Mark has by the fraction he gave to his friend.

Mark has $$4 \frac{1}{5}$$ yards of rope. To convert this mixed number to an improper fraction, we multiply the whole number part by the denominator and add the numerator.

4 \frac{1}{5} = \frac{(4 \times 5) + 1}{5} = \frac{20 + 1}{5} = \frac{21}{5}

Now, we need to find $$\frac{1}{3}$$ of $$\frac{21}{5}$$.

\frac{1}{3} \times \frac{21}{5} = \frac{1 \times 21}{3 \times 5} = \frac{21}{15}

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 3.

\frac{21}{15} = \frac{21 \div 3}{15 \div 3} = \frac{7}{5}

However, we can simplify this fraction further by converting it to a mixed number.

\frac{7}{5} = 1 \frac{2}{5}

Conclusion

In conclusion, Mark gave his friend $$1 \frac{2}{5}$$ yards of rope.

Answer

The correct answer is A. $$1 \frac{2}{5}$$
