) The City Sights tour company had the same ratio of tourists to guides on both days this weekend. On Saturday, there were 120 tourists and 18 guides. On Sunday, there were 40 tourists.) How many guides were there on Sunday?
If the ratio of tourists to guides on both days was the same, we can set up a proportion to solve for the number of guides on Sunday.
Let's let "x" represent the number of guides on Sunday.
We can set up the following proportion:
120 tourists / 18 guides = 40 tourists / x guides
Cross multiplying, we get:
120x = 18 * 40
Simplifying, we have:
120x = 720
Dividing both sides of the equation by 120, we find:
x = 720 / 120
x = 6
Therefore, there were 6 guides on Sunday.
