It depend on the definition of day, solar day or stellar day

Solar day:
#1# #"day"# #= 24 h#
#7# #"day"# =#7*24 h=168 h#

Stellar day:
#1# #"day"# #=# #23# #"hours"# #56# #"minutes"# #"and"# #4.1# #"seconds"# #=#

#=23+56/60+4.1/3600 h=23.934472222 h#

#7# #"day"# #=7*23.934472222 h=167.541305556 h#

Since you are are asking for decimal form, I suppose you defined the day as stellar day. If you are interested click here.

#7 color(white)(.) days#

#1 color(white)(.) day = 24 color(white)(.) hours#

So, we want the units of #days# to cancel out so we're left with #hours#:

#7 color(white)(.) cancel(days) * (24 color(white)(.) hours)/(1 color(white)(.) cancel(day))#

#168 color(white)(.) hours#
