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:

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