In Gloria’s class, 14 students’ favorite drink is lemonade. If this is 2/3 of the class, how many students are in the class?

To find the total number of students in Gloria's class, we can set up a proportion:

14 students is 2/3 of the class
Let x be the total number of students in the class.

Therefore, we have:
14 = (2/3)x

To solve for x, we can multiply both sides of the equation by 3 to get rid of the fraction:
14 * 3 = 2x
42 = 2x

Now, divide both sides by 2 to solve for x:
x = 42/2
x = 21

Therefore, there are 21 students in Gloria's class.
