Step 3: From step 1, it follows that {100\%}={81}.

Step 4: In the same vein, {x\%}={ 18}.

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

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

{x\%}={ 18}(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}{ 18}

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

\frac{x\%}{100\%}=\frac{ 18}{81}

\Rightarrow{x} = {22.22\%}

Therefore, { 18} is {22.22\%} of {81}.

Solution for 81 is what percent of 18:

81: 18*100 =

(81*100): 18 =

8100: 18 = 450

Now we have: 81 is what percent of 18 = 450

Question: 81 is what percent of 18?

Percentage solution with steps:

Step 1: We make the assumption that 18 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\%}={ 18}.

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

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

{100\%}={ 18}(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{ 18}{81}

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

\frac{x\%}{100\%}=\frac{81}{ 18}

\Rightarrow{x} = {450\%}

Therefore, {81} is {450\%} of { 18}.
