What is the value of 0.75 seconds expressed in terms of reaction time?

• A. 1/2 second
• B. 3/4 second
• C. 1 second
• D. 1 and 1/4 seconds

Answer: (B)

The value of 0.75 seconds corresponds directly to three-quarters of a second. When expressing decimal values in fractional terms, 0.75 can be converted to a fraction by recognizing that it is equivalent to 75/100, which simplifies down to 3/4. Therefore, when asked to express 0.75 seconds as a reaction time, identifying it accurately as 3/4 seconds aligns perfectly with the definition and conversion of the decimal value into a fraction. In the context of reaction time, which often involves understanding short periods of time required to respond to stimuli, 3/4 of a second is a clear and precise representation of the value given. This forms an important baseline for training, teaching, or assessing response times in various contexts, making the choice of 3/4 second not only correct but also relevant to understanding human reaction time dynamics.
