Question: 0.4 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\%}={0.4}.

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

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

{x\%}={0.4}(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}{0.4}

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

\frac{x\%}{100\%}=\frac{0.4}{21}

\Rightarrow{x} = {1.9047619047619\%}

Therefore, {0.4} is {1.9047619047619\%} of {21}.

Solution for 21 is what percent of 0.4:

21:0.4*100 =

(21*100):0.4 =

2100:0.4 = 5250

Now we have: 21 is what percent of 0.4 = 5250

Question: 21 is what percent of 0.4?

Percentage solution with steps:

Step 1: We make the assumption that 0.4 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\%}={0.4}.

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

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

{100\%}={0.4}(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{0.4}{21}

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

\frac{x\%}{100\%}=\frac{21}{0.4}

\Rightarrow{x} = {5250\%}

Therefore, {21} is {5250\%} of {0.4}.
