Answer:
35 students in the class.
Step-by-step explanation:
If there are 5 students in the class, then 2 of them would wear glasses and 3 of them wouldn't. (Equation 1)
Now, there are 14 students how are wearing glasses.
We just times the whole Equation 1 by 7.
If there are 5 x 7 = 35 students in the class, then 2 x 7 = 14 of them would wear glasses and 3 x 7 = 21 of them wouldn't.
So, there are 35 students.
