(6 5/6) * 1 hour= (6 * 6 + 5)/6 * 60 minutes
= 41/6 * 60 minutes
= 41 * 10 minutes
= 410 minutes
410 minutes + 103 minutes
= 513 minutes
513 minutes
= 513/60 hours
= 8 33/60 hours
33/60 hour
= 33/60 hour * 60 minutes
= 33 minutes
∴ (6 5/6) * 1 hour + 103 minutes = 8 hours and 33 minutes

6 5/6 is 41/6 of an hour. 41/6 x 60 minutes = 60(41/6)=410 minues
410+103= 513 minutes
Divide by 60 = 8.55
0.55 minutes = 0.55 times 60 = 33 minutes
8 hrs 33 min
410+103= 513 minutes
Divide by 60 = 8.55
0.55 minutes = 0.55 times 60 = 33 minutes
8 hrs 33 min

An hour is 60 minutes so
(5/6) * 60 = (5*60)/6 = (5*6*10)/6 = 50
(5/6) * 60 = (5*60)/6 = (5*6*10)/6 = 50

1 hr = 60 min
(5/6)(60) = 50 min
50 + 103 = 153 min = 120 min + 33 min = 2 hr 33 min
(5/6)(60) = 50 min
50 + 103 = 153 min = 120 min + 33 min = 2 hr 33 min

First, find out how many minutes 5/6 of an hour is. Use normal conversion math:
(5/6) hr * 60 min/hr = 50 min
Now, add that to your 103 minutes:
50 + 103 = 153.
Now, to convert that back to hours, convert it back:
153 min * (1/60 hr/min) = 2.55 hr.
So we have 2 hours, and a partial. Take that partial, convert it back to min:
0.55 hr (60 min/hr) = 33
The sum is 2 hours, 33 minutes.
(5/6) hr * 60 min/hr = 50 min
Now, add that to your 103 minutes:
50 + 103 = 153.
Now, to convert that back to hours, convert it back:
153 min * (1/60 hr/min) = 2.55 hr.
So we have 2 hours, and a partial. Take that partial, convert it back to min:
0.55 hr (60 min/hr) = 33
The sum is 2 hours, 33 minutes.

1 hr = 60 minutes
5/6 hr = x/60 minutes
x = 50 minutes
50 minutes + 103 minutes = 153 minutes
153 minutes / 60 minutes/hr = 2 hours 33 minutes
5/6 hr = x/60 minutes
x = 50 minutes
50 minutes + 103 minutes = 153 minutes
153 minutes / 60 minutes/hr = 2 hours 33 minutes

5/6Ã60=50
50+103=153
that is 153 min,or 2 hours and 33 min.
50+103=153
that is 153 min,or 2 hours and 33 min.
