Step 3: From step 1, it follows that {100\%}={15}.

Step 4: In the same vein, {x\%}={129}.

Step 5: This gives us a pair of simple equations:

{100\%}={15}(1).

{x\%}={129}(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

\frac{100\%}{x\%}=\frac{15}{129}

Step 7: Taking the inverse (or reciprocal) of both sides yields
