Answer :
if you take 3.5 and divide it by 0.05, or times 20, that would make it 70.
100%/x%=3.5/5
(100/x)*x=(3.5/5)*x - we multiply both sides of the equation by x
100=0.7*x - we divide both sides of the equation by (0.7) to get x
100/0.7=x
142.85714285714=x
x=142.85714285714
now we have:
5 is 142.85714285714% of 3.5
