#### Explanation:

Well, we're given that the hole drains

#(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d"))#

Now we perform this division, and afterward the denominator will be **number of liters drained per day**:

#(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" ")|)#

Therefore,
