Answer 1

8часов 12минут-5часов 35 минут=

492мин - 335мин=157мин=

2 час 37 мин

Answer 2

(60*8+12)-(60*5+35)=492-335=157минут= 2часа37минут

Answer 3

To subtract 5 hours 35 minutes from 8 hours 12 minutes, you need to perform the subtraction for each unit (hours and minutes) separately.

Subtracting hours: 8 hours - 5 hours = 3 hours

Subtracting minutes: 12 minutes - 35 minutes = -23 minutes

Since the result for minutes is negative, we need to borrow 1 hour from the 3 hours.

3 hours - 1 hour = 2 hours

Now, we have 2 hours and -23 minutes as the result. However, we want to represent the result as a positive number of minutes, so we need to convert the hours back to minutes.

2 hours * 60 minutes/hour = 120 minutes

Finally, add the minutes:

120 minutes - 23 minutes = 97 minutes

So, 8 hours 12 minutes - 5 hours 35 minutes = 2 hours 97 minutes, which can be simplified to 3 hours 37 minutes.
