If 18 students occupy 3/5 of the seats in the classroom, how many students would occupy 2/3 of the seats in the room?

Answer 1

First, we need to get the total number of seats in the classroom. Let's call that number "S". We know that 18 students occupy 3/5 of the seats, which means that 2/5 of the seats are not occupied. We can set up the equation:

18 = (3/5)S

To solve for S, we can multiply both sides by 5/3:

S = 18 x (5/3)

S = 30

So there are 30 seats in the classroom.

Now we need to figure out how many students would occupy 2/3 of those seats. To do this, we need to multiply the total number of seats by 2/3:

(2/3) x 30 = 20

Therefore, 20 students would occupy 2/3 of the seats in the classroom.
