1/25-3:27/25

I’m not sure how to read that expression. Could you clarify what you mean? Here are two common possibilities and their results: 1) If it’s simple fraction subtraction: (1/25) − (3/25) - Result: -2/25 2) If “3:27” is a time (3 minutes 27 seconds) and you intend (1/25) − (3:27)/25, treating times as hours: - 3:27 = 3 minutes 27 seconds = 207 seconds = 23/400 hours - (3:27)/25 = (23/400) ÷ 25 = 23/10000 hours - 1/25 hour = 400/10000 hours - Difference: 400/10000 − 23/10000 = 377/10000 hours If you can confirm which interpretation matches your problem (or provide the exact statement), I’ll compute it precisely and show the steps.
