(.90*100):21 =

90:21 = 4.29

Now we have: .90 is what percent of 21 = 4.29

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} = {4.29\%}

Therefore, {.90} is {4.29\%} of {21}.

Solution for 21 is what percent of .90:

21:.90*100 =

(21*100):.90 =

2100:.90 = 2333.33

Now we have: 21 is what percent of .90 = 2333.33

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} = {2333.33\%}

Therefore, {21} is {2333.33\%} of {.90}.
