Question: 40 is what percent of 221?

Percentage solution with steps:

Step 1: We make the assumption that 221 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\%}={221}.

Step 4: In the same vein, {x\%}={40}.

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

{100\%}={221}(1).

{x\%}={40}(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{221}{40}

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

\frac{x\%}{100\%}=\frac{40}{221}

\Rightarrow{x} = {18.1\%}

Therefore, {40} is {18.1\%} of {221}.

22100:40 = 552.5

Now we have: 221 is what percent of 40 = 552.5

Question: 221 is what percent of 40?

Percentage solution with steps:

Step 1: We make the assumption that 40 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\%}={40}.

Step 4: In the same vein, {x\%}={221}.

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

{100\%}={40}(1).

{x\%}={221}(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{40}{221}

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

\frac{x\%}{100\%}=\frac{221}{40}

\Rightarrow{x} = {552.5\%}

Therefore, {221} is {552.5\%} of {40}.
