FTCE General Knowledge Math Practice Test

Which of the following represents the conversion of 1 foot?

1. 30 cm

2. 0.9 m

3. 1 yd

4. 3 ft

The correct answer is: 0.9 m

The correct answer, which indicates the conversion of 1 foot, is that it is equivalent to 0.9 meters. This relationship arises from the fact that 1 foot is defined as exactly 0.3048 meters. When rounded to one decimal place, this value is approximately 0.9 meters. Each of the other options represents a different measurement that does not match the conversion of 1 foot. For instance, 30 centimeters is approximately equal to 11.8 inches or 0.3937 feet, which is less than 1 foot. One yard is equal to 3 feet, so it does not equate to just 1 foot. Lastly, 3 feet is simply three times the length of 1 foot, which clearly exceeds it. Therefore, the most accurate representation of 1 foot from the provided choices is 0.9 meters.
