  1. Good job Reiner, you just did decimals and percent wrong because decimals are always over 1 and percent is always out of 100. You also forgot to include the converting part and the part where you change a fraction into a decimal.

  3. Good job Reiner! You did a couple of things wrong. What you need to fix are that the decimals are always over 1 and that percent is always out of 100. You also forgot to add how to show fractions into decimals. Right idea, better than last time!

  6. Nice post, Reiner. I had a hard time following your examples. I found it kind of messy. A percent isn't anything that's 100, but out of 100. You forgot to capitalize somethings. You also forgot to post what we learned about converting fractions.
