If 1 days work is 7 hours. How long is 0.8 days?
answer:
you can use ratio and proportion.
if 1 day is to 7 hours therefore 0.8 days is to __?
solution:
1 day / 7hrs. = 0.8 day / H
H = 0.8 day x 7 hrs. / 1 day *(cancel day unit)
H = 5.6 hrs = 5 hrs. and 36 mins.
if 1 day is to 7 hours therefore 0.8 days is to 5.6 hrs or 5 hrs. and 36 mins.
enjoy math:-)

0.1 of a day is 0.7 of an hour
0.1 of an hour is 6mins
0.7 of an hour 6 mins x 7 = 42 mins = 0.1 of a day
so 0.2 of a day is 84 mins = 1 hour 24 mins
to find 0.8 days - 1 - 0.2 days
= 7 hours - 1 hour 24 mins
= 5 hours 36 mins
