Question: .45 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\%}={.45}.

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

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

{x\%}={.45}(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}{.45}

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

\frac{x\%}{100\%}=\frac{.45}{21}

\Rightarrow{x} = {2.14\%}

Therefore, {.45} is {2.14\%} of {21}.

Solution for 21 is what percent of .45:

21:.45*100 =

(21*100):.45 =

2100:.45 = 4666.67

Now we have: 21 is what percent of .45 = 4666.67

Question: 21 is what percent of .45?

Percentage solution with steps:

Step 1: We make the assumption that .45 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\%}={.45}.

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

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

{100\%}={.45}(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{.45}{21}

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

\frac{x\%}{100\%}=\frac{21}{.45}

\Rightarrow{x} = {4666.67\%}

Therefore, {21} is {4666.67\%} of {.45}.
