Solution for -10 is what percent of 21:

-10:21*100 =

(-10*100):21 =

-1000:21 = -47.62

Now we have: -10 is what percent of 21 = -47.62

Question: -10 is what percent of 21?

Percentage solution with steps:

Step 1: We make the assumption that 21 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\%}={21}.

Step 4: In the same vein, {x\%}={-10}.

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

{100\%}={21}(1).

{x\%}={-10}(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{21}{-10}

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

\frac{x\%}{100\%}=\frac{-10}{21}

\Rightarrow{x} = {-47.62\%}

Therefore, {-10} is {-47.62\%} of {21}.

Solution for 21 is what percent of -10:

21:-10*100 =

(21*100):-10 =

2100:-10 = -210

Now we have: 21 is what percent of -10 = -210

Question: 21 is what percent of -10?

Percentage solution with steps:

Step 1: We make the assumption that -10 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\%}={-10}.

Step 4: In the same vein, {x\%}={21}.

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

{100\%}={-10}(1).

{x\%}={21}(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{-10}{21}

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

\frac{x\%}{100\%}=\frac{21}{-10}

\Rightarrow{x} = {-210\%}

Therefore, {21} is {-210\%} of {-10}.
