Convert to improper fractions; get common denominators; cancel the common denominators away. Divide as normal.

The answer is 4.
Explanation:
The question is asking: how many times can you take
You can think of it this way: say you have a piece of string
To do this division, we need to convert both the top fraction and the bottom fraction to the same denominator (or "units").
#2 1/2" "=" "4/2 + 1/2" "=" "color(red)(5/2)#
and
#color(red)(5/2)" "=" "5/2xx1" "=" "5/2 xx 4/4" "=" "20/8#
So our question is now
#" "(20/8 )/(5/8)#
So, how many times can we take
In other words:
#(" "20/8" ")/(5/8)=20/5# ,
which is 4.
