## Thinking Mathematically (6th Edition)

Consider the proportional relation between the alligator’s tail length and the body length. Because, the alligator with a body length of 4 feet has 3.6 feet tail length. So, the alligator with a body length of 1 foot will have $\frac{3.6}{4}\ \text{feet}$ tail length. This shows that the alligator with a body length of 6 feet has $\left( \frac{3.6}{4}\times 6 \right)\ \text{feet}$ tail length. It is solved as, \begin{align} & T=\frac{3.6}{4}\times 6 \\ & =5.4\ \text{feet} \end{align} Hence,an alligator with body length of 6 feet has tail length of 5.4 feet.
