Charleston cut three acres of grass at the meadowbrook farm, which is 15% of the property. how many acres are on the meadowbrook farm?

The answer is:  " 20 acres " .

Explanation:

3 is 15% of "x" ;  solve for "x" .

15/100  = 0.15 .

(0.15)x = 3 ;

Multiply BOTH SIDES of the equation by "100" ; to get rid of the decimal value;

100* { (0.15)x = 3} ; 

15x = 300 ; 

Divide each side of the equation by "15" ;
  to isolate "x" on one side of the equation; & to solve for "x" (in acres) ;

15x/15 = 300/15 ; 

    x = 20 .

The answer is:  " 20 acres " .
