Sarah ran her first mile in 8 minutes. Her next mile was run in 6 minutes.

What was the percent decrease in her mile time?

percentages :/ I believe you have to calculate that 8 is 100 and 6 is unknown so

8=100
6=x

what times 8 gets you too 100? 12.5, so multiply
6*12.5=75

therefore Percent decrease=75%

realize I am a seventh grader and practicing my math and by this it would seem you are a seventh grader too. I hope this helped, if you need anymore Just post here. i'll bookmark this.

Keep practicing your math, Madeline. Your answer is wrong.

8 - 6 = 2

2/8 = 1/4 = 25%

Thanks, I was only trying

Yes, but your trying could have messed up another person. Do not post answers here unless you are absolutely sure.

BOTH of you. Thanks.

25% would be what is left after 75%?

75% + 25% = 100

Correct?

The decrease in her mile time is 25%. 75% has nothing to do with it.

To calculate the percentage decrease in Sarah's mile time, you need to find the difference between her initial time and final time, and then calculate what percentage that decrease represents.

1. Find the difference in time:
Initial time - Final time = 8 minutes - 6 minutes = 2 minutes

2. Calculate the percentage decrease:
Percentage decrease = (Difference / Initial time) * 100

In this case, the initial time is 8 minutes, and the difference is 2 minutes:
Percentage decrease = (2 / 8) * 100 = 25%

Therefore, Sarah's mile time decreased by 25%.
