the answer is C, to figure it out take all the numbers and multiply by .10

Answer:

Option C.

Explanation:

Let the unknown number be x.

It means 10% of x is 81.

\(x\times \dfrac{10}{100}=81\)

\(x\times \dfrac{1}{10}=81\)

\(\dfrac{x}{10}=81\)

Multiply both sides by 10 to find the value of x.

\(\dfrac{x}{10}\times 10=81\times 10\)

\(x=810\)

The value of x is 810. It means 10% of 810 is 81.

Therefore, the correct option is C.
