<span>we know that if 95 is out of 100%, we can write it down as 95 = 100%. w</span><span>e also know that x is 20% of the output value, so we can write it down as x = 20%. </span> now we have the equations: 95=100% x=20% next we will put the equations together 95/x = 100%/20% 95/x=100/20 <span>(95/x)*x=(100/20)*x </span>we multiply both sides of the equation by x <span>95=5*x </span>now we divide both sides of the equation by 5 to get x <span>95/5=x </span> <span>19=x </span> x=19 we now know that <span>20% of 95 = 19 let me know if you have any other questions :)</span>
