Answer:

#0.875# #"L/d"#

Explanation:

Well, we're given that the hole drains #color(red)(3.5color(white)(l)"L"# in #color(green)(4color(white)(l)"d"#, so we can write the rate as

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

Now we perform this division, and afterward the denominator will be #1# and thus it will tell us the 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, #color(blue)(0.875color(white)(l)"liters"# are drained every day on average.
