At lunch, 17 students drank lemonade. This represented 20% of the student on the field trip. How many students were on the field trip?

0.2x = 17

x = 17/0.2
x = ?

20 To find the total number of students on the field trip, we can use the information given - that 17 students drinking lemonade represents 20% of the total number of students.

Let's call the total number of students on the field trip "x".

We can set up a proportion to solve for x. Since 17 is 20% of x, we can write the proportion as:

17/x = 20/100

To solve this proportion, we can cross multiply:

17 * 100 = x * 20

1700 = 20x

Now, we can solve for x by dividing both sides of the equation by 20:

1700/20 = x

x = 85

Therefore, there were 85 students on the field trip.
