\\(\frac{3 feet}{1 yard}=\frac{? feet}{7 yards}\\)
convert.
7 yards = feet

Explanation:

We know that 1 yard = 3 feet.

Step2: Set up proportion

The correct proportion to convert yards to feet is $\frac{3\text{ feet}}{1\text{ yard}}=\frac{?\text{ feet}}{7\text{ yards}}$.

Step3: Solve proportion

Cross - multiply: $1\times(?\text{ feet})=3\times7$. So, $?\text{ feet}=21$.
