At first, to convert 645 minutes to hours and minutes, we have to convert 645 minutes into hours.
To change 645 minutes into its equivalent number of hours and leftover minutes, we first need to calculate the total hours component of the 645 minutes by performing division by the constant 60 minutes per hour.
645 minutes / 60 minutes
⇒ 645 minutes x 1/60 hours = 10.75 hours [as 1 minute = 1/60 hours]
Now from the above number we come to know that the whole number part which is in the left side of the decimal point is the number of hours which is 10.
Therefore the number of hours = 10
Now we have to find out the remaining minutes. To acheive this we can simply take the decimal part 0.75 and convert it into minutes. In this case we need to convert 0.75 hours in minutes to calculate the remaining minutes. For this we need to muitiply 0.75 hours by 60 minutes.
0.75 hours X 60 minutes = 45 minutes
Hence, combining the values of hours and minutes calculated above, we can conclude that
645 minutes = 10 hours and 45 minutes
Therefore the final result for the query 645 minutes in hours and minutes is equivalent to 10 hours and 45 minutes.
