- Add this result to the number of full hours.
📌 Example Calculations
Let’s walk through a few examples to solidify your understanding.
Example 1:
Input: 2 hours, 15 minutes
Calculation:
2 + (15 ÷ 60) = 2 + 0.25 = 2.25 hours
Example 2:
Input: 1 hour, 45 minutes
Calculation:
1 + (45 ÷ 60) = 1 + 0.75 = 1.75 hours
Example 3:
