I was having my high school students work on exponential equations today with the growth and decay factors and I realized they really needed some work on converting decimals to percents and back so I created this little warm up sheet. I hope it helps. It can be used with high school students as a warm up activity or with middle school students working on this skill. 20 problems. Answer key included, 2 pages. This can be used as a warm up, class work, homework, or even as an assessment. Enjoy!
