Let the variable x represent the answer.
85% [tex]= 0.85 = 85 / 100 [/tex]
[tex]120/x=100/85[/tex]
[tex](120/x)*x=(100/85)*x [/tex]
- we multiply both sides of the equation by x
[tex]120=1.17647058824*x [/tex]
- we divide both sides of the equation by (1.17647058824) to get x
[tex]120/1.17647058824=x [/tex]
[tex]
x=102[/tex]
