See a solution process below:

First, we can combine the percents as:

#(85 + 12 -37)% => (97 - 37)% => 60%#

"Percent" or "%" means "out of 100" or "per 100",

Therefore 60% can be written as #60/100#.

We can reduce this as:

#60/100 => (3 xx 20)/(5 xx 20) => (3 xx color(red)(cancel(color(black)(20))))/(5 xx color(red)(cancel(color(black)(20)))) => 3/5#.

#color(blue)(3/5)#

If N be any real number, then:

#N%=N/100#

#:.#

#85%=85/100\ \ \ # , #12%=12/100# , #\ \ \ \37%=37/100#

#85/100+12/100-37/100#

Adding the fractions:

#(85+12-37)/100=60/100=6/10=color(blue)(3/5)#
