Answer:

See the entire solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore 20% can be written as #20/100# and 25% can be written as #25/100#.

When dealing with percents the word "of" means "times" or "to multiply".

We can now write this expression as:

#(20/100 xx 90) -: (25/100 xx 36)#

#(20/100 xx 90)/(25/100 xx 36)#

#(1800/100)/(900/100) -> 18/9 -> 2#
