Now we have: 21 is what percent of 1020 = 2.06

Question: 21 is what percent of 1020?

Percentage solution with steps:

Step 1: We make the assumption that 1020 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\%}={1020}.

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

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

{100\%}={1020}(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{1020}{21}

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

\frac{x\%}{100\%}=\frac{21}{1020}

\Rightarrow{x} = {2.06\%}

Therefore, {21} is {2.06\%} of {1020}.

Solution for 1020 is what percent of 21:

1020:21*100 =

(1020*100):21 =

102000:21 = 4857.14

Now we have: 1020 is what percent of 21 = 4857.14

Question: 1020 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\%}={1020}.

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

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

{x\%}={1020}(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}{1020}

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

\frac{x\%}{100\%}=\frac{1020}{21}

\Rightarrow{x} = {4857.14\%}

Therefore, {1020} is {4857.14\%} of {21}.
