### Sheila's Scribe Post

1) Kaitlyn and Jordan are converting 0.003 to a percent. Who's correct? Show how you know.

Kaitlyn: 0.003 = 3%
Jordan: 0.003 = 0.3%

Jordan is CORRECT!
Kaitlyn's thinking: I think that she thought that since 0.003/1000, that you needed to multiply the number 1000 to get the right answer. But she was wrong. And she did 0.003x 1000= 3%. That's how she got the answer.

Jordan's way is right! Because he multiplied 0.003 with 100 and not 1000.

This is what Kaitlyn did:

And this is what Jordan did:

And if you need more help on converting a decimal into a fraction here's the link to the video.
2) Change each decimal to a percent and a fraction.

3) Several years ago Clarie bought the first issue of a popular comic book for \$10.
At a recent auction, it sold for \$200. What percent is the new value of the comic book of the price several years ago?

And if your in the mood for some more percents, decimals, and fractions than here's a link!

1. AWESOME JOB Sheila! your explanations for how you answered the questions were very clear. I like your pictures that you took they helped me a lot. Smart idea on taking a picture of your calculator. also your links helped to.

2. Thanks for Scribing. Good Post. Creative use of a calculator

3. Sheila, great post！I liked the way you took pictures of your calculator which shows us how you did the calculations. But I don't agree with your explanation for question 3, I would show a proportion of 10\$ over 100%, and 200\$ over 2000%. Because 200\$ is 20 times more than 10\$, so I would multiply the bottom by 20 too. Then I would also end up with 2000%, but this is explained differently and the number have different meanings. Keep working, Sheila!

4. Awesome job Sheila! I liked how you took pictures of your calculator, it also explained how you did the calculations. I also liked how you showed us how to convert a decimal into a percent and a fraction. But your link was not as helpful as your information. Here is a link that I think you might like:

6. Hi Sheila, AWESOME scribe post!! I liked that your explanations were clear and were easy to read. I liked that you took picture of your calculator to show us what you did, it was a very smart and creative idea. But I have to agree with Cindy. The way Cindy explained it was easier to understand.

9. GREAT JOB sheila! i like your picture and i liked how you showed your work on a calculator. Your link is helpful However, on question 2 the pictures isn't very clear and sort of small but you did a great job anyways. Here is a video because you don't have one:

10. What's up, Sheila? You did a FABULOUS job on your scribe post. The solution to the questions were all explained very clearly and is very easy to understand. You added some pictures and a link which is good, but next time you should add a video, too. Also, for question 3, you said that 200 divided by 100 is 20, but it's actually 2. So you might want to fix that. It's alright though. You still did a fantastic job. Keep working hard and you'll be smart like your cousins, Irena and Serena. Good job Lam!
