Increase or decrease 32 pages to 28 pages round to the nearest tenth of a percent

Hello! I would love to help!

Let's start by decreasing 32 pages to 28. How many pages does it take to get from 28 to 32? Let's subtract to find out!

32-28=4

Okay, now we know 28 pages is 4 less than 32.

Now, what percentage did it decrease by? Let's find out by dividing!

4/32=0.125

Let's make that decimal into a percentage by multiplying it by 100.

0.125*100=12.5

So, we now know the answer is...

decreased by 12.5%

Hope this helped! Comment if you have questions!
