Answer
$8\text{ yards}$
Work Step by Step
Use the conversion rate $1 \text{yard} = 3 \text{ feet}$ by multiplying $\frac{1\text{ yard}}{3\text{ feet}}$ to obtain:
$\require{cancel}
24\text{ ft}
\\= 24\text{ ft} \cdot \frac{1\text{ yard}}{3\text{ ft}}
\\= \cancel{24\text{ ft}}^8 \cdot \frac{1\text{ yard}}{\cancel{3\text{ ft}}}
\\=8\text{ yards}$
