The eight grade has decreased over the past 15 years from 850 students to 739 students what is the perfect decrease

U mean percent decrease?
If so, the answer would be about 13.06 percent I think

Hello! For this question I'll be mostly doing the math needed for the problem and add some notes to let you know what's going on!

850-739=111
111/850

(For this part of the math, the biggest number goes first in the equation, but the original number is the denominator)

111/850=0.13...

(You would now move the decimal to the right two times to get the percent change)

0.13 ---> 01.3 ---> 13 ---> 13%

So the number of students from the past 15 years has decreased 13%

I hope this helps!!!

The answer is
