Question: -109 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\%}={-109}.

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

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

{x\%}={-109}(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}{-109}

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

\frac{x\%}{100\%}=\frac{-109}{81}

\Rightarrow{x} = {-134.57\%}

Therefore, {-109} is {-134.57\%} of {81}.
