Step 3: From step 1, it follows that {100\%}={21}.

Step 4: In the same vein, {x\%}={7.8}.

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

{100\%}={21}(1).

{x\%}={7.8}(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{21}{7.8}

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

\frac{x\%}{100\%}=\frac{7.8}{21}

\Rightarrow{x} = {37.142857142857\%}
