The enrollment of Kennedy High School dropped from 1200 to 1000 over a three-year period. What the percent of decrease during this time?

A. 20
B 16 2/3
C. 25
D. 200
E. 2

My answer is 1200-1000=200

200/1200= 1/6 ( some wrong )

Right.

To find the percent, multiply:

0.1666666 * 100 = 16 2/3%

You need to find the decimal answer. Use a calculator.

the decimal answer is 0.1666666

oh, I get it now, thank you

Yay! :-)

You're welcome.

To find the percent decrease, you need to calculate the decrease in enrollment as a percentage of the original enrollment.

First, calculate the decrease in enrollment by subtracting the final enrollment (1000) from the initial enrollment (1200):

1200 - 1000 = 200

Next, divide the decrease (200) by the original enrollment (1200) and multiply by 100 to get the percentage decrease:

(200 / 1200) * 100 = 16.67

So the percent decrease in enrollment over the three-year period is approximately 16.67%.

Therefore, the correct answer is B) 16 2/3.

That's not the answer I got when I divided 200 by 1200.
