100%/x%=40/26
<span>(100/x)*x=(40/26)*x - W</span>e multiply both sides of the equation by x
<span>100=1.53846153846*x - W</span>e divide both sides of the equation by (1.53846153846) to get x
<span>100/1.53846153846=x </span>
<span>65=x </span>
x=65
<span>Now we have: </span>
<span>26 is 65% of 40
