Solution for -1 is what percent of 40:

-1:40*100 =

(-1*100):40 =

-100:40 = -2.5

Now we have: -1 is what percent of 40 = -2.5

Question: -1 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\%}={-1}.

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

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

{x\%}={-1}(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}{-1}

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

\frac{x\%}{100\%}=\frac{-1}{40}

\Rightarrow{x} = {-2.5\%}

Therefore, {-1} is {-2.5\%} of {40}.

Solution for 40 is what percent of -1:

40:-1*100 =

(40*100):-1 =

4000:-1 = -4000

Now we have: 40 is what percent of -1 = -4000

Question: 40 is what percent of -1?

Percentage solution with steps:

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

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

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

{100\%}={-1}(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{-1}{40}

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

\frac{x\%}{100\%}=\frac{40}{-1}

\Rightarrow{x} = {-4000\%}

Therefore, {40} is {-4000\%} of {-1}.
