the common denominator is 6x
we multiply the first term by 2x/2x and the second term by 3/3
(x+1)/3 * 2x/2x - (x+2)/2x* (3/3)
2x(x+1) /6x- (x+2)*3/6x
distribute
(2x^2+2x -3x-6 )/6x
(2x^2-x-6)/6x
The numerator is (2x^2-x-6)
Set up a proportion
45/225= x/100
45/225 simplifies to 1/5.
1/5= x/100
5*20=100
1*20=20=x
Final answer: 20%
