Explanation:
If you write the proportion as ratios of feet to yards, you have ...
![\frac{3\,\text{ft}}{1\,\text{yd}}=\frac{12\,\text{ft}}{4\,\text{yd}}\\\\\boxed{(3)/(1)=(12)/(4)}\qquad\text{without the units}](https://img.qammunity.org/2021/formulas/mathematics/college/oqqggpece0yszcds02pr75qcv95rwjymap.png)

Please note that a proportion is a true statement. Here, you need only pick the true statement from those offered. For example, here's the first choice written in more readable form:
![(12)/(1)=(4)/(12)\qquad\text{FALSE statement}](https://img.qammunity.org/2021/formulas/mathematics/college/o0zduybmeef1zhe225ji8r3xfo5k6hzhr7.png)
