Solution for 81 is what percent of -81:

81:-81*100 =

(81*100):-81 =

8100:-81 = -100

Now we have: 81 is what percent of -81 = -100

Question: 81 is what percent of -81?

Percentage solution with steps:

Step 1: We make the assumption that -81 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\%}={-81}.

Step 4: In the same vein, {x\%}={81}.

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

{100\%}={-81}(1).

{x\%}={81}(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{-81}{81}

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

\frac{x\%}{100\%}=\frac{81}{-81}

\Rightarrow{x} = {-100\%}

Therefore, {81} is {-100\%} of {-81}.

Solution for -81 is what percent of 81:

-81:81*100 =

(-81*100):81 =

-8100:81 = -100

Now we have: -81 is what percent of 81 = -100

Question: -81 is what percent of 81?

Percentage solution with steps:

Step 1: We make the assumption that 81 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\%}={81}.

Step 4: In the same vein, {x\%}={-81}.

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

{100\%}={81}(1).

{x\%}={-81}(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{81}{-81}

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

\frac{x\%}{100\%}=\frac{-81}{81}

\Rightarrow{x} = {-100\%}

Therefore, {-81} is {-100\%} of {81}.
