A school has 850 students and each classroom has 25 seats. How many classrooms are needed?

We know there are 850 students and each classroom has 25 seats. To calculate how many classrooms are needed to seat 850 students, we need to divide 850 by 25. We can’t divide eight by 25, so we need to move to the next digit, 85 divided by 25. How many 25s are there in 85? The closest we can get to 85 is 75. Three times 25 is 75. So, let’s write our three.

And we know that three times [25] is 75. 85 take away 75 leaves us with a remainder of 10. We can’t divide 10 by 25, so we need to bring down the zero. Now, we can calculate 100 divided by 25. There are four 25s in 100, which leaves us with no remainder. 850 divided by 25 equals 34. If a school has 850 students and each classroom has 25 seats, they will need 34 classrooms.
