54=75/100*x where x is the number. So 54=3x/4 and 216=3x and x=216/3=72. Check: 3/4 of 72=3*18=54.
"I'm pretty sure this is right but if doesn't add up to what your looking for I'm sorry."
This is how my math teacher taught me

54 is 75 percent of what?
pretend what = x
54 is 75% of x
separate the question so that "is" "%" and "of" have their own number
54 is | 75% | of x

do this formula
is/of (fraction) = %/100(fraction)

this formula works too
is = %/100(fraction) x of

Hope this helped
