Step 3: From step 1, it follows that {100\%}={90}.

Step 4: In the same vein, {x\%}={128}.

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

{100\%}={90}(1).

{x\%}={128}(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{90}{128}

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