Clay's dinosaur footprint is 3 times longer than Patrick's dinosaur footprint. It takes 18 paperclips to measure Clay's dinosaur footprint. How many fewer paperclips would it take to measure Patrick's dinosaur footprint?

 

C = Clays Dinosaur

P = Patricks Dinosaur 

 

We have c = 3p (1)

We also have c = 18 (2)

(1) = (2) => 3p = 18

p = 6 (3)

|(2)-(3)| = |18-6|=12 fewer
