Cheryl's Scribe Fraction Scribepost

#1.            3 1/6 divided by 1 2/3

 First you have to put it as a question. 
How many groups of 1  2/3 go into 3  1/6 ?

 When you're done that you have to estimate if your answer will be less than 1 or greater than 1

My estimate was that the answer will be greater than 1.

Next, you write it as a fraction.


You should change the mixed fractions into improper. 
 








When you finished writing it into a fraction, you have to make the denominator reciprocal. Once you've made the denominator reciprocal you have to make the numerator reciprocal too. After that you have to multiply the numbers at the numerator and at the denominator.

 Change 19/10 into a mixed fraction and you should get 1  9/10


# 2.        2/9 divided by 5/6

How many groups of 5/6 go into 2/9 ?

My estimate: Less than 1
 

Write it as a fraction

 Make them reciprocal, and then multiply them.



  

# 3.  1/10 divided by 1/5
 How many groups of 1/5 go into 1/10?

  My estimate: Greater than 1
 

Write as fraction

 Make the fractions reciprocal and then multiply.

If this didn't really help you then here's a website and game that could help you understand dividing fractions better.

  1. Great job Cheryl! Your work is very well explained, I like how you did everything step by step. The diagrams you created are also well done. The game and video are helpful to better understand dividing fractions. Next time I suggest you make diagrams that actually prove how many times 1/5 goes into 1/10 (just used it as an example) Everything else is great!

  2. Nice work Cheryl! I like how your explanation was clear and very descriptive. I also liked how you added in a video to have a clear indication on how to divide fractions. Next time I suggest you actually add a pictorial representation of dividing fractions. Overall, excellent job!

  4. Good job cheryl I can see that you put alot of work on your scribepost, one part I got confused was at the part when you were explaining about the reciprocals. I now know what you are trying say but i Think you should have worded it like this "Then you have to multiply the denominator by its reciprocal, and what ever you do to one sided you do to the other."
    Also next time I would suggest that you would show why you made that choice on estimating. Overall you did a good job.
