Answer :

To determine whether the statement "1 yard = 3 feet" is true, let's walk through the process of converting yards to feet.

1. Identify the relationship between yards and feet: We know from the conversion factors used in everyday measurements that 1 yard is equal to 3 feet.

2. Example Conversion: Let's say we want to convert 3 yards to feet.
- We start with the quantity in yards, which is 3 yards.
- Since we know that 1 yard equals 3 feet, we can multiply the number of yards by the number of feet per yard to find the equivalent length in feet.

3. Perform the calculation:
[tex]\[ 3 \text{ yards} \times 3 \frac{\text{feet}}{\text{yard}} = 9 \text{ feet} \][/tex]

4. Conclusion: Given that the calculation results in 9 feet, and we know the relationship 1 yard = 3 feet holds true based on these conversions, we can say that the statement "1 yard = 3 feet" is accurate.

Therefore, the answer to whether the ratio 1 yard to 3 feet is true is:
True.
