Question: 81.5 is what percent of 30?

Percentage solution with steps:

Step 1: We make the assumption that 30 is 100% since it is our output value.

Step 2: We next represent the value we seek with {x}.

Step 3: From step 1, it follows that {100\%}={30}.

Step 4: In the same vein, {x\%}={81.5}.

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

{100\%}={30}(1).

{x\%}={81.5}(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{30}{81.5}

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

\frac{x\%}{100\%}=\frac{81.5}{30}

\Rightarrow{x} = {271.66666666667\%}

Therefore, {81.5} is {271.66666666667\%} of {30}.
