The class size increased 25% to 40 students. what was the original class size?

The original class had 32 students. 25% of 32 is 8 and 32+8=40

Hello, I would love to help!

Alright. First, let's figure out what the problem means.

We need to find 25% of 40, then subtract that number from 40 to find your answer, because the class increased by 25%.

Okay, let's find 25% of 40.

To do that, we need to multitasking the decimal form of 25% (0.25) by 40.

0.25*40=10

Okay, so now we know the class increased by 10 kids. Let's subtract those kids from the new class to find the original class number.

40-10=30

So, the original class size was 30 students.

Answer= 30 students

Hope this helped, comment if you have any questions! :)
