### Olivia's Textbook Question

Question #11, 2.3 Problem Solving With Rational Numbers in Fraction Form

Things you will need to know to help you solve this question:
- a jiffy = 1/100 of a second or 0.01 of a second
- Naima types 50 words in 1 minute
- 1 minute is 60 seconds
- s stands for seconds, w stands for words

The main goal is to find out how many jiffies it takes Naima to type 1 word.

First you divide 60 by 50 to find out how many seconds it takes her to type one word:

60s/50w = 1.2s per 1w

*You can't have a decimal in a fraction, I meant to write 60/50 = 1.2.

How I got 1.2s per 1w:

The next step is to find out how many jiffies (0.01s or 1/100s) are in 1.2s. You convert 1.2s into a fraction.

1.2s as an improper fraction is:

To find out how many jiffies are in 1.2s you divide 1 1/5 by 1/100.

1. Great job Olivia! I think you used the colours wisely and also used good diagrams. You also solved the question in a way that was easy for me to understand. Last but not least, I think it was good that you made a scentence to state the answer.

2. Good job Olivia! I like how you changed the color of the important words. the part that confused me is when you put 1 1/5 divided by 1/100. the one and one fifth looked like 11/5. Overall good job.

3. Great Job Olivia! I really like your pictures! They are very clear. I like how you explain how you got your answers. Also you used different colors to make the words pop out.

4. great job Oliva i like how you put pictures, colors in your post and you explained your answers so keep it up

5. Great job, Olivia! I like how you colour coded the important words, but as a suggestion, I recommend that you should use around 3-4 colours, as it would be less distracting and confusing. The pictures are clear, as with the explanations. Keep up the good work!
