Find what percent one number is of another

Full solution

Q. Fill in the missing number.

\newline

\_\_\_\_\%

of

90

=

90

Set up equation: Set up the equation to find the percentage. $\newline$ Let $x$ be the percentage we are looking for. The equation is: $\newline$ $x$ % of $90$ = $90$ $\newline$ This translates to: $\newline$ $(x/100) \times 90 = 90$
Solve for x: Solve for x. $\newline$ Divide both sides by $90$ to isolate $\frac{x}{100}$ : $\newline$ $\frac{x}{100} = \frac{90}{90}$ $\newline$ $\frac{x}{100} = 1$
Convert to percentage: Convert the decimal to a percentage. $\newline$ Multiply both sides by $100$ to find $x$ : $\newline$ $x = 1 \times 100$ $\newline$ $x = 100$
