1800:40 = 45

Now we have: 18. is what percent of 40 = 45

Question: 18. 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\%}={18.}.

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

{100\%}={40}(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{40}{18.}

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

\frac{x\%}{100\%}=\frac{18.}{40}

\Rightarrow{x} = {45\%}

Therefore, {18.} is {45\%} of {40}.

Solution for 40 is what percent of 18.:

40:18.*100 =

(40*100):18. =

Now we have: 40 is what percent of 18. = 222.22222222222

Question: 40 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\%}={40}.

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

{100\%}={18.}(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{18.}{40}

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

\frac{x\%}{100\%}=\frac{40}{18.}

\Rightarrow{x} = {222.22222222222\%}

Therefore, {40} is {222.22222222222\%} of {18.}.
