Question: .87 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\%}={.87}.

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

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

{x\%}={.87}(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}{.87}

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

\frac{x\%}{100\%}=\frac{.87}{21}

\Rightarrow{x} = {4.14\%}

Therefore, {.87} is {4.14\%} of {21}.

Solution for 21 is what percent of .87:

21:.87*100 =

(21*100):.87 =

2100:.87 = 2413.79

Now we have: 21 is what percent of .87 = 2413.79

Question: 21 is what percent of .87?

Percentage solution with steps:

Step 1: We make the assumption that .87 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\%}={.87}.

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

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

{100\%}={.87}(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{.87}{21}

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

\frac{x\%}{100\%}=\frac{21}{.87}

\Rightarrow{x} = {2413.79\%}

Therefore, {21} is {2413.79\%} of {.87}.
