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 $hours$ :

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

$168 color(white)(.) hours$
