Explanation:

Step1: Find total stickers distributed

Subtract remaining stickers from total: $142 - 2 = 140$

Step2: Calculate number of students

Divide distributed stickers by per - student stickers: $\frac{140}{15}$? Wait, no, wait. Wait, the problem says each student received 15? Wait, no, wait, 142 - 2 = 140, then 140 divided by 15? Wait, no, maybe I misread. Wait, the total stickers are 142, left 2, so distributed is 140. Each student gets 15? Wait, 140 divided by 15 is not integer. Wait, maybe the per - student is 14? Wait, no, let's re - check. Wait, the problem: "A class collected 142 stickers. They divided the stickers equally among the students. Each student received 15 stickers, and 2 stickers were left. How many students shared the stickers?" Wait, no, 15 n+2 = 142. So 15n = 142 - 2 = 140. Then n = 140 / 15? That can't be. Wait, maybe it's 14? Wait, 1410 + 2=142? No. Wait, maybe the per - student is 10? No. Wait, maybe I made a mistake. Wait, 142 - 2 = 140. If each student gets 14, then 140/14 = 10. But the problem says 15. Wait, maybe the problem has a typo, but according to the problem, let's do it as per the numbers. Wait, 142 - 2 = 140. Then number of students n = 140 / 15? No, that's not possible. Wait, maybe the per - student is 14. Wait, maybe the original problem has 14. But as per the given problem, let's proceed. Wait, 15n+2 = 142 => 15n = 140 => n = 140/15≈9.33. That's not possible. Wait, maybe the total is 142, left 2, so distributed 140. If each student gets 10, 14 students. But the problem says 15. Wait, maybe I misread the per - student number. Wait, maybe it's 14. Let's assume that maybe it's a typo and the per - student is 14. Then 140/14 = 10. But according to the problem as given, let's do the calculation. 142 - 2 = 140. Number of students = 140 / 15? No, that's wrong. Wait, maybe the problem is 142 stickers, left 2, each student gets 10, then 14. But the problem says 15. Wait, maybe I made a mistake. Wait, let's re - write the equation: Let the number of students be n. Then 15n+2 = 142. So 15n = 140. n = 140/15 = 28/3≈9.33. That's not possible. So maybe the per - student is 14. Then 14n+2 = 142 => 14n = 140 => n = 10. Ah, maybe the problem has a typo, and "15" is "14". But as per the given problem, let's proceed with the numbers. Wait, maybe the user made a typo, but according to the steps:

Step1: Calculate stickers given to students

Total stickers - remaining stickers = 142 - 2 = 140

Step2: Calculate number of students

Number of students = stickers given to students / stickers per student = 140 / 15. But this is not an integer. Wait, maybe the problem meant 14 stickers per student. Then 140/14 = 10.

Assuming that maybe it's a typo and the per - student is 14, then the number of students is 10. But as per the given problem with 15, it's not possible. But maybe I misread. Wait, the problem says "divided the stickers equally among the students. Each student received 15 stickers, and 2 stickers were left". So the equation is 15n+2 = 142. Solving for n:

15n = 142 - 2 = 140

n = 140/15 = 28/3≈9.33. Which is not a whole number, so there must be a mistake. But maybe the total is 142, left 2, so 140, and per - student is 14, then 10 students.

Answer:

Assuming a possible typo and per - student stickers as 14 (or if we consider the problem as is, there is an error, but if we proceed with 140/14), the number of students is 10. But as per the given numbers (15), the calculation gives a non - integer, which is not possible for number of students. If we follow the equation 15n + 2=142, the number of students is $\frac{140}{15}=\frac{28}{3}\approx9.33$, but since the number of students must be an integer, there is a mistake in the problem. However, if we assume that the per - student stickers are 14, the number of students is 10.
