Question

1. what scale relates a shamu stuffed animal (18 inches long) to the real shamu (40 feet long)?

Explanation:

Step1: Convert real - Shamu's length to inches

Since \(1\) foot \( = 12\) inches, then \(40\) feet \(=40\times12 = 480\) inches.

Step2: Calculate the scale

The scale is the ratio of the length of the stuffed animal to the length of the real Shamu. The scale \(s=\frac{\text{length of stuffed animal}}{\text{length of real Shamu}}\).
So \(s=\frac{18}{480}\). Simplify the fraction: \(\frac{18\div6}{480\div6}=\frac{3}{80}\)

Answer:

The scale is \(3:80\)
