84/x=100/75
(84/x)*x=(100/75)*x - we multiply both sides of the equation by x
84=1.33333333333*x - we divide both sides of the equation by
(1.33333333333) to get x
84/1.33333333333=x
63=x
x=63
This means that 75% of $84 is $63
An easier way to explain it is:
75% is equivalent to 75 / 100
75% of $84 is: (75 / 100) * $84
