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?
Answered by Madeline
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
Answered by Ms. Sue
Yes, but your trying could have messed up another person. Do not post answers here unless you are absolutely sure.
Answered by Geek Girl
BOTH of you. Thanks.

25% would be what is left after 75%?

75% + 25% = 100

Correct?
Answered by Ms. Sue
The decrease in her mile time is 25%. 75% has nothing to do with it.
