Question: .040 is what percent of 18?

Percentage solution with steps:

Step 1: We make the assumption that 18 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\%}={18}.

Step 4: In the same vein, {x\%}={.040}.

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

{100\%}={18}(1).

{x\%}={.040}(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{18}{.040}

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

\frac{x\%}{100\%}=\frac{.040}{18}

\Rightarrow{x} = {0.22\%}

Therefore, {.040} is {0.22\%} of {18}.

Solution for 18 is what percent of .040:

18:.040*100 =

(18*100):.040 =

1800:.040 = 45000

Now we have: 18 is what percent of .040 = 45000

Question: 18 is what percent of .040?

Percentage solution with steps:

Step 1: We make the assumption that .040 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\%}={.040}.

Step 4: In the same vein, {x\%}={18}.

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

{100\%}={.040}(1).

{x\%}={18}(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{.040}{18}

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

\frac{x\%}{100\%}=\frac{18}{.040}

\Rightarrow{x} = {45000\%}

Therefore, {18} is {45000\%} of {.040}.
