-1:28*100 =

(-1*100):28 =

-100:28 = -3.57

Now we have: -1 is what percent of 28 = -3.57

Question: -1 is what percent of 28?

Percentage solution with steps:

Step 1: We make the assumption that 28 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\%}={28}.

Step 4: In the same vein, {x\%}={-1}.

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

{100\%}={28}(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{28}{-1}

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

\frac{x\%}{100\%}=\frac{-1}{28}

\Rightarrow{x} = {-3.57\%}

Therefore, {-1} is {-3.57\%} of {28}.

Solution for 28 is what percent of -1:

28:-1*100 =

(28*100):-1 =

2800:-1 = -2800

Now we have: 28 is what percent of -1 = -2800

Question: 28 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\%}={28}.

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

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

{x\%}={28}(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}{28}

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

\frac{x\%}{100\%}=\frac{28}{-1}

\Rightarrow{x} = {-2800\%}

Therefore, {28} is {-2800\%} of {-1}.
