.5:21*100 =

(.5*100):21 =

50:21 = 2.38

Now we have: .5 is what percent of 21 = 2.38

Question: .5 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\%}={.5}.

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

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

{x\%}={.5}(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}{.5}

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

\frac{x\%}{100\%}=\frac{.5}{21}

\Rightarrow{x} = {2.38\%}

Therefore, {.5} is {2.38\%} of {21}.

Solution for 21 is what percent of .5:

21:.5*100 =

(21*100):.5 =

2100:.5 = 4200

Now we have: 21 is what percent of .5 = 4200

Question: 21 is what percent of .5?

Percentage solution with steps:

Step 1: We make the assumption that .5 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\%}={.5}.

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

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

{100\%}={.5}(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{.5}{21}

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

\frac{x\%}{100\%}=\frac{21}{.5}

\Rightarrow{x} = {4200\%}

Therefore, {21} is {4200\%} of {.5}.
