Hi Ms. Sue, it was 20%. Thank you for your help, though! You are still my favorite website to go on! =)
Thank you. :-)
Don't feel bad for yourself Ms. Sue! You are an awesome teacher. It's me, I should be really learning more into this subject. =)
Aaarrgghh! I had a brain malfunction! I see what I did wrong.
15/75 = 0.2 = 20%
I found on the rare occasions that I taught math that I was only about 95% accurate. I was embarrassed, but told my students that I'd give them extra credit if they found an error that I made on the board and politely told me about it.
