Question: .21 is what percent of 90?

Percentage solution with steps:

Step 1: We make the assumption that 90 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\%}={90}.

Step 4: In the same vein, {x\%}={.21}.

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

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

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

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

\frac{x\%}{100\%}=\frac{.21}{90}

\Rightarrow{x} = {0.23\%}

Therefore, {.21} is {0.23\%} of {90}.

Solution for 90 is what percent of .21:

90:.21*100 =

(90*100):.21 =

9000:.21 = 42857.14

Now we have: 90 is what percent of .21 = 42857.14

Question: 90 is what percent of .21?

Percentage solution with steps:

Step 1: We make the assumption that .21 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\%}={.21}.

Step 4: In the same vein, {x\%}={90}.

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

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

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

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

\frac{x\%}{100\%}=\frac{90}{.21}

\Rightarrow{x} = {42857.14\%}

Therefore, {90} is {42857.14\%} of {.21}.
