Answer:
1.67%
Step-by-step explanation: There are 60 minutes in an hour, and percent means per hundred. Based on that, we can make the following formula to convert any minutes of an hour to a percentage:
(100 × Minutes) ÷ 60 = Percentage
Now, when we enter 1 minute into our newly created formula, we get the answer to "What percentage of an hour is 1 minute?" like this:
(100 × Minutes) ÷ 60 = Percentage
(100 × 1) ÷ 60 = Percentage
100 ÷ 60 ≈ 1.67
1 minute of an hour as a percentage ≈ 1.67%
