A boy who is \( 3 \) feet tall can cast a shadow on the ground that is \( 7 \) feet long. How tall is a man who can cast a shadow that is \( 14 \) feet long? 

Set up the proportion by doing ratios of height to length of shadow. 

\(x / 14 = 7 / 3 \) 

\( 7 / 14 = x / 3 \) 

\( x / 3 = 14 / 7 \) 

\( 3 / x = 14 / 7\) 

Answer

\(\frac{x}{3} = \frac{14}{7}\)
