You would use 2 number lines to compare fractions because if you were trying to see which fraction was larger than you would use a number line.
As a practical equation, this one doesn't make much sense -- why would the profit per person have a term proportional to the number of people? Let's just go with it.



That's the answer to the first part.
35/x represents a portion of the profit that's 35/x per person, or a constant $35 per tour.
The rate would be
22000 gallons per 16 hours or
rate = 22000/16 = 1375 gallons/hr
Answer: 12 inches

Step-by-step explanation:
<u>Similar Triangles</u>
By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:
