Question: .81 is what percent of 20?

Percentage solution with steps:

Step 1: We make the assumption that 20 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\%}={20}.

Step 4: In the same vein, {x\%}={.81}.

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

{100\%}={20}(1).

{x\%}={.81}(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{20}{.81}

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

\frac{x\%}{100\%}=\frac{.81}{20}

\Rightarrow{x} = {4.05\%}

Therefore, {.81} is {4.05\%} of {20}.

Now we have: 20 is what percent of .81 = 2469.14

Question: 20 is what percent of .81?

Percentage solution with steps:

Step 1: We make the assumption that .81 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\%}={.81}.

Step 4: In the same vein, {x\%}={20}.

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

{100\%}={.81}(1).

{x\%}={20}(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{.81}{20}

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

\frac{x\%}{100\%}=\frac{20}{.81}

\Rightarrow{x} = {2469.14\%}

Therefore, {20} is {2469.14\%} of {.81}.
