Write Ratio in Fraction Form: Write the ratio of $7$ staff members to $9$ campers in fraction form. $\newline$ $7$ staff members / $9$ campers = $\frac{7}{9}$ $\newline$ Fraction form of the first ratio: $\frac{7}{9}$
Write Ratio for $18$ Staff and Campers: Write the ratio of $18$ staff members to $18$ campers in fraction form. $\newline$ $18$ staff members / $18$ campers = $\frac{18}{18}$ $\newline$ Fraction form of the second ratio: $\frac{18}{18}$
Simplify Second Fraction: Simplify the second fraction. $\frac{18}{18} = \frac{1}{1}$ Simplified form of the second ratio: $\frac{1}{1}$
Compare Fractions: Compare the two fractions to see if they are equal. $\newline$ First fraction: $\frac{7}{9}$ $\newline$ Second fraction: $\frac{1}{1}$ $\newline$ Since $\frac{7}{9}$ is not equal to $\frac{1}{1}$ , the ratios do not form a proportion.
