16. You will get a smaller number.  Explanations will vary.  Since you will be starting with a smaller unit, fluid ounces, and going to a larger unit, gallons, the number will get smaller because you are multiplying by a fraction less than one.
    
    
17. A larger number.  Explanations will vary.  Since you will start with a larger unit, miles, and converting to a smaller unit, feet, the number will get larger because you are multiplying by a number greater than one.
    
    
18. Explanations will vary. Sophie crossed off the 2 cups without actually doing the division.  If the 2 cups was crossed off, the 22 should have been divided by 2 to get 11.  The answer should have been 11/ 2 or 5 ½ quarts.
    
    
19. Examples will vary.  The conversions are set up correctly, but the error is when 3 is crossed off and 22 is not divided by 3.  Answer should be 22/3 or 7 1/3 yards.

264 in. x  1 foot   x    1 yard  =  11 yards
                12 in.          3 feet
