Find what percent one number is of another

Full solution

Q. Fill in the missing number.

\newline

\_\_\_\_\_\%

of

80

=

80

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 $80$ = $80$ $\newline$ This translates to: $\newline$ $(x/100) \cdot 80 = 80$
Solve for x: Solve for x. $\newline$ Divide both sides of the equation by $80$ to isolate $x$ : $\newline$ $(\frac{x}{100}) = \frac{80}{80}$ $\newline$ $\frac{x}{100} = 1$
Convert to percentage: Convert the decimal to a percentage. $\newline$ Multiply both sides by $100$ to find the percentage: $\newline$ $x = 1 \times 100$ $\newline$ $x = 100$
