2. On a map, if one centimeter represents 25 kilometers, how many kilometers does 7 centimeters represent?

3. Observe the five tiger images labelled A, B, C, D, and E. Which set of images look similar, and which ones look different?

4. Do images B and E look like the other three images (A, C, and D)?

5. Which statement best explains why images A, C, and D appear similar while B and E look different?

6. Using the measurements Image A = 60 mm by 40 mm, Image B = 40 mm by 20 mm, Image C = 30 mm by 20 mm, Image D = 90 mm by 60 mm, and Image E = 60 mm by 60 mm, which image is a square?

7. From image A (60 mm by 40 mm) to image D (90 mm by 60 mm), by what common factor are both the width and height multiplied?

8. By what factor should the ratio 60 : 40 (image A) be multiplied to obtain 90 : 60 (image D)?

9. What is the simplest form of the ratio of width to height for image B, which is 40 : 20?

10. What is the simplest form of the ratio of width to height for image E, which is 60 : 60?
