Convert 15 Minutes to Hours: Time Unit Conversion Problem

To convert 15 minutes to hours, we will use the conversion factor that 1 hour equals 60 minutes. Our task is to determine how many hours 15 minutes represents.

• Step 1: Start with the given number of minutes, which is 15 minutes.
• Step 2: Use the conversion formula, which states that the number of hours is equal to the number of minutes divided by 60. This is because there are 60 minutes in one hour.
• Step 3: Apply the formula: $\text{hours} = \frac{\text{minutes}}{60} = \frac{15}{60}$
• Step 4: Simplify the fraction $\frac{15}{60}$ by dividing the numerator and the denominator by their greatest common divisor, which is 15.
• Step 5: Simplify $\frac{15}{60}$ to $\frac{1}{4}$.

Therefore, 15 minutes is equivalent to $\frac{1}{4}$ hours.

The correct answer is $\frac{1}{4}$.
