Fill in the missing number.

% of 900 = 810

1 answer

To find the missing percentage, we can set up the equation based on the information given:

Let \( x \) be the percentage we are trying to find. The equation can be set up as follows:

\[ \frac{x}{100} \times 900 = 810 \]

Now, solve for \( x \):

  1. Multiply both sides by 100:

\[ x \times 900 = 81000 \]

  1. Divide both sides by 900:

\[ x = \frac{81000}{900} \]

  1. Calculate \( \frac{81000}{900} \):

\[ x = 90 \]

Thus, the missing percentage is \( 90% \).
